I'm curious about this myself. Not to give false hope, but I noticed while poking around in NHL98, that the Carolina Hurricanes graphics and roster data were located in the spot between Florida and Los Angeles [where Hartford should be]. So while I know this is possible, in 96-98 at least, it would be related to pointers somewhere in the hex data. The only tiny issues here being that this is assuming that this knowledge is even transferable to the 94 game engine and I have no idea where to find that data anyway.
That said, if it turns out that this isn't possible, I would be willing to volunteer my services to rearrange the graphics. I have a player card EARE companion "tool" that I've been looking to test more anyway. At least that would make the player photos a bit less bother to rearrange.
