Spring Relocation without mini tub...

Has anyone done the 3in inboard spring kit without mini tub? I want to get some more space for a 315/60/15 tire which is Tire Diameter:30.00 in.
Section Width:12.90 in.
Tread Width:11.90 in.

I want to also be able to lower the rear so that the lip of the wheel well covers part of the tire for the pro street look. Is this possible to do with only the spring relocation kit and possibly moving the rear back 1 inch?

The reason for not wanting to mini tub is, I have the fold down rear seat option and there isn't that much room to work with when trying to keep that and cutting the original wheel wells.

I kinda want this look below:
