I have a sense of where you're going with that. It's going to be very difficult to pull off a logical plot twist, and it's going to be even more so to write that without slipping into tedium. The idea still seems a little shaky.
It sounds interesting like something would read. a historical fiction, however it sounds like it might get to close to the idea of captain America with super soldiers so you would have to take it a whole different direction to avoid giving the readers something they havn't seen before
