Art-wise I thought of that too... just swap one of the female pilots for Blair. However with WC2 you would also need to end up re-recording a bunch of dialogue - particularly in the intro - to allow for the gender change. There's a number of other voiced cutscenes as well IIRC. WC2 also has a couple of cutscenes that are an early animation format. The Blair/Angel kiss isn't an issue if those are the characters you are swapping. As far as I can tell the game just mirrors people depending on if they are on the left or right... I'm not sure if that presents any problems for Blair's different uniform in the WC2 intro or not. The other animation that would need art would be the takeoff/landing animations when the canopy opens/closes, but that's an issue for both WC1 and 2.
