Obviously you can't do that.
I'm saying is it possible to start with a MIM Duo Sonic, and end up with this:

It doesn't have to be a 1964 model. It could be an earlier one like that with the other pickguard.
What I'm saying is that will reissue parts fit a MIM Duo Sonic? Like, if I bought a pickguard would it work out?
Basically, if I bought a MIM Duo Sonic, could I use its body and neck to completely retrofit it? Would parts meant for a 1960s Duo Sonic fit a 1993 Duo Sonic?
