Just ideas, contour the body and put in a Jem style monkey grip. Spray it blood red and replace the binding with real ebony to practice wood bending. Reshape the back of the neck (been said already I think), install a fender S1 switch and see how many pickup combinations you can make. Rout out a battery cavity and build an active booster circuit, and finally strip it all back and reverse engineer everything you've done and start over. Filling in cavities for trems and holes is hard to do well I'm told.
