I'm sure you can get it all to fit under the stock body just fine, but it may be more work than you want to do. You may require additional under hood clearance, so maybe a higher hood, you may need wider fender wells to fit the wheels under the car without them looking akward, etc. You can probably do whatever you want with the doors and some other things, but best to hold off/just plan how you want things to look for much of the body.
