What do you mean "skin" doorhandles? Do you mean shave your doorhandles? If so wait a few and there will be a full exsplanation and instruction on the How to website, after it gets posted I'll give you the link.
As for a system, any will work, its not model biased. Just look around there are thousands out there.
F-1 Rodder is right, you need to have some way of manually opening the doors. You don't want them to have to cut the doors in half just to get you out or what if your battery runs down. Its a fun thing to do but I wouldn't do it on a daily driver unless I could rig a way to manually open them. Instead of going full shaved, try retro fitting some handles from newer cars that are flush with the body, if possible. That would definetely be unique.
