In reply to mike123:
I've done this on a pair of skis ~105mm and skins cut for skis about 65 at the waist.
It works fine on easy slopes and in soft snow. As soon as the snow gets firm, or you have to skin up a steeper hill on a traverse it becomes a total nightmare and you'll spend most of your time sitting in the snow screaming with rage (well, I did anyway) before having to walk.
I've never tried cutting the skins, that it supposed to work reasonably well. Otherwise you may have to bootpack sections that others can skin, depending on the conditions. If you're touring in the UK then having to walk a bit isn't going to be a major problem.
