Are there any HP customs out there?

[Marty]

I'm after either decals or picture of original lego made customs, as I'm having trouble getting the original ones from the old HP sets.

What I would like is the following;

Mad-eye Moody
Sirius Black
Lupin
Worm-tail
Umbridge

It's a tall-order I know, but I'm sure some of you will have already tried to make these before, and I know based on how the original figures where created, some of the pieces still exist in other sets, so I would welcome your help in any way.
Regards Marty
