Cutting gas tank, doing side exhaust, adding rear diffuser.

Well you would have to put the evap canister back in there and hook it all back up as it was! Your other option is to make your own fuel tank vent and route it upward somewhere maybe by the filler neck and put a rollover valve on it so it doesnt dump fuel if the car finds itself upside down.

Be warned though - cars with open ventilation fuel tanks stink like fuel vapor! I have a very sensitive nose and it would annoy me personally, but im sure plenty of people dont mind.

Over the years I have seen plenty of people just drill a big hole in the gas cap for ventilation after removing all the OEM stuff. The downside here is there is no rollover protection. You may want to check rule books to make sure this wouldnt disqualify the car should it receive a detailed tech exam.
