It's more a matter of weight, I think. The pod has to be a 
self-contained structure for the times it's on the ground by itself, and

the lift vehicle has to be a complete structure for when it's not 
carrying a pod. So at the connection between them, there's twice as much

structure as there needs to be if it's a non-podded design, which is
heavy.

Oh, I dunno... As someone suggested earlier, why not use the "dynamics" 
of the Mantis -- engines, tail, even the cockpit if you think in-line 
seating is appropriate (though most transports have side-by-side 
seating; not all, though -- look at the Mi-24 /Hind/ which, though famed

as a gunship, could also carry troops) -- and add a custom-built 
fuselage for the transport mission. To take another example from the 
real world, think H-1 "Huey". The original Huey gunships were converted 
transports used to cover "slicks" (unarmed troop transports) on 
insertion and retrieval missions; later, the AH-1 HueyCobra was 
designed, replacing the UH-1 fuselage with a specialist body for the 
gunship role. Why not do something similar for the Mantis, only in
reverse?

I like the idea of using pods/modules, but I also have to admit that it 
will have its drawbacks.
