Anything is possible given the right player or modification! However perhaps you mean "are there region 1/2 only players on general sale?" in which case I'm not sure - usually they're either locked to a specific region (or perhaps combinations of region as you ask) or are multi-region in that they can read all media or can be switched between regions without limits.
Yeah - but the original question was whether or not it was possible to buy a player off the shelf that coped with two or more regions but wasn't actually region free.
