Another tire/wheel question

I know, I know…another tire and wheel question. It should go in the tire/wheel forum…but I wanted 570 specific answers, so here I am.

I’ve done the math and even drawn a few pictures. I think I’ve found a way to upgrade tires and wheels with no need for spacers, no rubbing, and keeping the 570 at 50". I just want to run the setup by you all to see if there is any additional input or something I’ve missed.

12×7 4+3 wheels up front
12×7 5+2 wheels in back

27×9-12 tires up front
27×11-12 tires in back

The wheels I’ve found are 12 lbs each and Zillas are 21.5 and 24.3 in those sizes. Minimal weight increase so I’m hoping to delay a clutch kit at this point.

The front and rear setup should each match the factory setup in terms of amount of tire inside of the hub and are each +1" on the outside.

I found another setup that would work with DWT Sector 3 wheels with 12" tires in back…but I’m not paying for DWT Sector 3 wheels.

Thoughts? Comments?
