Well, if someone already have done those rosters then it is possible. I don't know if anyone have done this? If you mean conversion for example from EA's NHL 2006-2007 game, that is not possible straight away. Anyways, you can use NHLInfo-editor and type those rosters by yourself, but it will take some time and you will also notice that attributes of players are not the same in newer games and NHL95PC.
