So I'm drunk and watching Evangelion and don't have anything else to do (yeah, yeah, E&C, you'll get your fluff by midnight

). So I thought I'd throw this one out as I'd been considering it today.
Fact #1: mechanized Marine formations suck somewhat as there is at best 1 extra transport space (not talking about variants like Salamanders with their extra Land Raiders and stuff, but vanilla marines and probably most variants too). Rhinos die from anyone looking at them harshly, and then marines who were riding inside must hoof it, thus slowing down the whole formation. Or, well, they die, but that's hardly a consolation.
Fact #2: Rhino is an exceptionally dependable vehicle in the fluff, and though it's not that hard to render inoperable it can recover - all by itself, frequently - from all kinds of damage in short order.
Idea: "Regenerating" Rhinos in a similar way to void shields. Say, during a Marshall order, for every 3 pips you get on the dice result (and thus could remove 3 Blast markers) you can get one Rhino back into operation instead, up to the maximum of the formation's initial allotment during the start of the battle.
Problems:
1) Bookkeeping required, at least to keep track what was the number of Rhinos a formation had at the start (doesn't happen if you keep your Rhinos distinctly marked for every formation of course

)
2) Um... discuss?
