You could always make a rules proposal and see what happens. I don't know if there's a bunch of resistance to it or not, but when I talk to people about it, they tend to not see much value to it. Tradition maybe, I don't know.

Glad to hear the RX is humming along well. I'm getting some really good runs out of my 120AX as I dial in my Aquila. That's one heck of a nice little engine and it drops right into the bolt pattern of a 140RX, though it is a little shorter.
