John Stallings got the up down windows ( and I think door swings also) with his walls (CR2) and Cal has the open door with his dishwasher ( and the shelf slides ) (PP2), so it is do-able either way. I wonder if it is not more of a rotate/trans thing rather than a morph. You may have problems with the prop distorting between 0 and 1.0 and again at greater than 1.0 if it is a morph.
