A commie all-x can probably get to the upper 20m range but usually will wind up maxing out at 25m. No one really does it with 90% jets though. It might be good to carry some jets, so people will respect the possibility of a retal, but all jets you may get hit more, and jets usually sell for less on the public market.
You also run into the problem of defensive allies, where if you are grabbed a lot due to running far less defense than would otherwise be normal. To retal then, you'd have to account for their defensive allies, whereas you likely won't be holding any offensive allies.
