oh dear - let's not start that mullarkey
it's doubtful otherwise they wouldn't need to re-orientate on a regular basis - even when they haven't moved.
Bees orientate nearly every day they leave the hive,they go out, buzz around a while getting their bearings then thin out; the problems start when you move the hive a little over three feet - then they'll just hunt around the space where the hive was. Just moving the entrance (as you are planning) would only mean them getting confused for a while before again finding the entrance which wouldn't be long if it's 'just next' to where it was yesterday, problem is, in this cold weather if you move the entrance too far (ie ninety or 180 degrees to where it was) by the time they find the entrance they may have chilled.
