Okay, I have kind of an idea for a WC-Remake. Now, I'm sure that the odds of this ever being done are nearly too low to calculate, but regardless, I'll post it anyway.
I was thinking about a WC-concept under the premise of a character similar to Lance Casey's character in WCP: Basically a pilot who's character would be the son/daughter of a WC1 character. The difference is that this character would have to be old enough to be able to participate in the last few years of the Kilrathi War.
Michael Casey (Iceman) could be used for this purpose: If he had a child when he was 21, he/she'd be born in 2644 and would be 21 in 2665 (around the start of WC2). Casey did have at least one child, a daughter, who was onboard a Kilrathi slave ship in 2654. I do not know if it explicitly stated that she was his only child, or how old she was, however.
Joseph Khumalo (Knight) would also be another character. He was born in 2618 and could easily have fathered a child by the late 2630's or early 2640's. Being born around that time would put them in their early 20's by the late 2650's or early 2660's. This wouldn't be too far off from WC-1, but you could have a story-line start between the years of WC-1 and WC-2, which were not touched upon much, then of course, continue to WC-2, WC-3, and so on.
Regarding the game-engine itself, I don't know exactly what I'd go for, but suffice it to say, I'd want to re-design the ships and fighters in WC-2 (possibly some in WC1) to give them a less cartoony look, combined with a better color-pallette similar to that seen in WC-3/WCP and so on, as well as re-scale the WC-2 fighters to a scale similar to that used in WC-1 and WC-3 -- this I've already come up with to some degree.
