Well, the helmet on that one would be fairly easy - use the head of a EU/Concept Speeder Bike pilot. Really neat flight-suits - I'd be tempted to use them - in a different paint scheme - as the Defense Boat pilots around Outland Station.
As for the TIE Pilot, man, that design is neat! I'm thinking maybe an Ironman head as a base, maybe one of the Ironman chests worked into a McFett. Almost has some echoes of a Snowtrooper in there, too. Those would be some neat ones to have, for sure. If they'd run those as comic-packs, some of us *ahem* would buy several packs just to have plenty of fodder to play with!
