3. Deformation is laughable
4. And its has enough adjustability to overcome tolerance stack / fit in the car

I will likely slot the main bracket and make the gussets slide it for weld, rerun it, then OSHcut here I come!

Fun stuff!

Are you planning on welding the bracket to the tank? You might check into 3M DP810 acrylic adhesive. We use it at my company for bonding lots of things where we need sanitation but can't have any distortion that full welds would cause. As long as you have the surface area it will hold.
