Lol. So that's what you're up too?
You could have pestered me for my M3 Bishonen Female morph, that way you can morph, and you'll be able to add M3 Bishonen Female into SnapeWear with WW2.  lol. I can imagine the mischief the boys played on Snape, but God Help them when Snape finds them. lol.  -^ 

I've already tried my young Snape with your Rickman Snape, and the two are totally compatible. ^^
You can even set Young Snape at 1.000 and add in .5000 of the Rickman and it gives pretty cool results. ^^
