I could change how close the trapezoids extend to the floor (shorten them by 0.5"), make some flanges on the bottoms of the trapezoids and then the floor clearance would be about 1" (currently .5"). Would this be a better alternative?

You want to change the sheet metal design -- by moving the gearbox up and changing the wheel, you'll lower the entire frame neared to the ground. Since a typically legal bumper height is between 1-7" or so from the ground, that puts the frame in the sweet spot.

Flanges on the bottom of the trapezoid won't really do anything useful to make the frame stiffer. A flange that runs, uninterrupted, along the entire bottom length -- just like you have on top -- is the most rigid solution.
