with take offs, it's easy. and hour job in the garage. and that is with a hand lug wrench! i haven't invested yet into a impact...make it faster.
the difference between winter tires and all season tires...is like trying to run a full sprint around a track with tennis shoes vs. track shoes. yes, the tennis shoes will do it, but, it could get a bit 'spirited' in the corners vs. the track shoes which are made for the track.
and don't forget, winter tires are more than just snow tires - they also help with traction at temps below 40 degrees...where all season's will lost a lot of traction below those temps. why they are called WINTER tires and not SNOW tires anymore.
