Though the idea is nice, like others said I don't think it's financially viable (as long as we expect a quality of at least IL-2's standards).
Furthermore, maybe it's only me, maybe I'm getting old, but maybe we should all move away from the 24 hours playing concept as it is too bad for our health
Most people say that are playing IL-2 only as a hobby, but in fact they are online at least 5 hours per day and spend at least another 5 hours per day with the game (in forums, skinning, etc.)
Trust me, this is not healthy and I don't want to imagine how many more junkies would be added if such a concept came in life lolol
Anyway, again as others said, most probably the SoW's engine is planned for exactly the interoperability that OP asks.
S!
