Bendeg, you can do whatever you want modifying it... I tell you that if you want to attack it with a router and then re-finish it, you can even put the new 32"or 30" scale neck on it... MODIFYING the thing.... But, in this case, it doesn't worth the while... believe me!
Might say that you have no idea of how it can work or not is because you don't have all the knowledge needed to make HEAVY modifications (or using routers, etc).... Would be better to you try to understand better how works the instruments, phisically speaking... Perhaps a good couple or triple read on "How to build your own electric guitar" By Mr Melvin Hiscock is a good try...
I believe that those heavy modifications are something that you have understand and think easy, with no effort (but with a lot of attention)... When you have hard time to understand, is better try things easier, learn more then try heavy thing...
By now, buying a neck and body, putting together is about a nice challenge, I believe...
