Hybrid vehicles - how likely/possible?

[raketenjagdpanzer]

I realize that "Going Home" and "Escape from Kalisz" aren't very far apart chronologically but there is three years of pretty savage road-warrior style combat going on in Central and East Germany, so I wonder how feasible it would be for local combat groups to engage in vehicle hybridization for the sake of firepower? Like, if a BMP1 hull was a write off, but everything in the turret still intact, could it be mated to a LAV25 hull with a reasonable hope of working?

I mean, obviously, "anything's possible" but I mean really, within the realm of feasibility.

I realize that some things (M1 hull with T72 turret for example) are out of the range of possibility but what kinds of things like that would be do-able? Assuming, say, the combat group in question had the mechanics with the skill and access to an M88 for lifting capability...

I ask because the Libyan uprising this past summer saw pickup trucks sporting BTR turrets, flat-bed trucks with SNEB rocket packs strapped on, and so forth.

I mean, if my choice as a commander of a unit that had until late 1998 had functioning tanks and I was about to be ordered to roll up the southern flank of the 143rd Guards Army in Central Poland and my choice was doing it with horses, motorcycles and humvees with a handful of command LAV25s and M113s to pick up the survivors or at least try to rebuild some of those vehicles as assault guns, I know what I'd do.
