Please read the last paragraph in my post again.
If 540 is to be recognised at any time, I believe it should be for the more novice drivers and a cheap class to run, so cars and equipment should reflect this so the new comer isn't frightened away. Now if any 540 racer is serious about the class and claims it is the fun thing to do, I am sure they won't mind going back to cheap basic equipment, including radios, speed controls and chassis. No carbon fibre, no unobtainium shocks, no super top end radios, basic cheap fun gear we all most likely started with.
