Kudos to you for having a plan and the fortitude to stick with it.
I think most people here, myself included I must admit, think it might be better on your hip pocket to go the other way, but it is your car and your money and you have an eye for the potential that you want out of it, so you can do whatever you like to it.
I can't wait to see the photo's and good luck with your project
(just don't put a GTR badge on it lol )
