Just a random idea. Cut the shrink wrap wrapper off the ESC. Find or make a little aluminum box the ESC fits into. Make an end plate on the box that has the needed wires pass through it, seal it up with silicone or bulkhead seals (if you're fancy). Throw a 3/8" nipple on each side of the box. Mount a little PC liquid cooling pump plumbed to the nipples so it has a high fluid flow rate through the ESC. Put the end on the box, sealed up with some silicone, fill the system with mobil1 oil, synthetic ATF, or if you wana get super fancy, fluorinert (a specially designed electronics cooling fluid).
The high flow rate of fluid should do a pretty good job of distributing the inherent hot spots in the controller into the whole system.
It might be enough to give the RC controllers decent reliability, maybe double the continuous safe current handling, and the total parts cost to give it a try is ~$50.
