Honestly, it sounds cumbersome. I think I see where you're going with the idea and it has merit, but would really reduce the playability I think. I often create a TF at a port get all the ships assembled and then change my mind. To me this just reflects a planning process that the command would go through. The ships aren't actually setting sail and then redocking.
I also agree that the idea has merit. To keep it playable, I'd say make the PP cost automatic (instead of several mouse clicks as it takes to change a unit's HQ now) and also include an undo function, up to 10-12 actions. Without an undo function, it would all be done on paper or you would need to make a new save after every move.
While none of us have seen the code, I'd suspect the first (making the cost automatic) would be relatively easy to implement but the second (undo function) would be a b----. Maybe we'll see this in WITP II or III.
