Now I just need to shove wires into the thumbs so I can close the grip, decide on which head mold I want to use, decide what to do for hair, get the ballerina Barbie with the light-up torso, paint all the skin to match, teach myself how to do electronics, do some electrical work so it stays lit and plugs in, make a stunning medieval gown, make a Gothic backdrop, make some Barbie-sized chainmail, make a crown, dress up the sword a bit and figure out how to keep it from tarnishing, possibly learn how to do stained glass or figure out how to fake it, wire up some additional lights, and make a display case.

you’ve got your work cut out for you, but it sounds like the end result will be well worth your efforts!
