It's a creative idea, but mobile homes really aren't designed for that. The biggest problem would be poorly-insulated floors suddenly exposed to the open air at elevation, although perhaps some skirting could be developed to interface with the frame or the house below. However it seems that the idiosyncratic plumbing, siding, roofing, heating, etc. components particular to this style of home would not be robust to lifting to or existing at the heights required. Also I doubt the fire codes would ever be amended to allow this scenario.
