I was thinking under the swing arm sort of where the center stand would mount or up a little higher like a later 850 Commando.
I was thinkin' of turnin' the plastic front air dam option into a fresh air intake, through a (very) thin plenum/shroud duct, to the remote mount oil cooler located somewhere just behind the oil filter.
Less ground clearance yes, but probably wouldn't affect cornering, and the duct would provide some road debris damage protection to both the existing oil filter and the relocated oil cooler. (as much protection as would be expected)

Dwight having an oil pan on his car with fins on it is just shocking!

due to the unexpectedly warm weather last weekend (which did not last) I got the speedy unwrapped from its winter cocoon and started looking and measuring for oil cooler location opportunities. What I have are some potentials, each with pluses and minuses: relocate the stock oil cooler to under the seat - if you airbox is already gone, there is room to fit the cooler. Could be a relocate or an add on. A fan would be a must. mount a cooler (4x7 inch max size)under the bike just back of the oil filter. there are 2 tabs on the frame to mount to. mount a oil filter relocate bracket somewhere and put a larger oil cooler under the bike. unfortunately the stock oil cooler will not fit under the bike. more thinking

Some years back (around year 2000) a Norton 750 Commando owner had added temperature sensors to his cylinder head and oil tank and recorded readings during a hot (95 F) summer day. The results were sobering. Head temperature reached 300 F on the freeway and 400 F when he entered city traffic to head home. As most of us know, motor oils break down fast above 250 F. As the Triumph motor is very similar to the Commando in displacement and configuration, it would appear that more oil cooling, not less, would help keeping oil temperatures in the "sweet spot" between 200 and 250 degrees F.
Of course, some "real world" measurements are preferred, and thermocouples and indicators are cheap. It would be low cost to hook up a sensor and indicator and then "Bluetooth" data orally back to the Wife at home to write down the observed temperatures.
The existing layout is not the best, as vertical twins are behind the front wheel, and the stock oil cooler interferes with air flow to the cylinders.
Case in point, look at the "air head" BMW twins from the early 70's. I have a1972 R75/5 and just one jug on it has about the same fin area as the modern air cooled Triumph for both cylinders.
In this case, get the data, find out how bad the operating temperatures are, and then add enough oil cooling to get the oil between 200 and 250 F, particularly on hot days.

well you could also look at this way - there are literally millions of collective miles on all these Triumphs with no oil associated problems

From "WRENCHIN'@RANDOM", HOTROD.COM/Marian-Davis, 10/13;
For a dual-purpose car, engine oil needs to be AT LEAST 220 degrees F to burn off all the deposits and accumulated water vapor. For every pound of fuel burned in an engine, the combustion process also generates a pound of water! If engine sump temperatures rarely exceed 212 degrees (water's boiling point), the water will mix with sulfur (another combustion by-product) and create acids that can eventually damage bearings.
As for ultimate power potential, the general consensus among most racers is that hot oil and cool water make more power in most engines. Cold engine oil causes excessive frictional drag on the bearings and cylinder walls. A quality conventional motor oil will tolerate oil sump temperatures of up to 250 degrees, but starts breaking down over 275 degrees. The traditional approach is to try to hold oil temperatures between 230 and 260 degrees, even on short duration...
A full-synthetic oil will withstand sump temperatures in excess of 300 degrees...
Car and motorcycle engines, Apples and Oranges? I think NOT. The science should be the same in ANY combination.

Now that's wisdom. I like it, makes a lot of sense. The engineers at Triumph are no idjits. There's a reason the oil cooler is where it is and is the size it is. Save your money and time and don't remove it or relocate it to the sissy bar or try to run it through tubing in your jacket.*
* now that might be a nice idea

I have been wondering about better cooling. Been using Mobil V-twin 20/50 since it came out, right after I bought bike in 02. They use to make Triumphs oil.
I noticed they now use castro oil. Will use it on next oil change, Bike seems to run hotter since I had 120,000 miles. Have 130,000 on it.

Forgot to mention, am planning to use a coil cleaner for ac units.
put out by Frost king and says good for car radiators
