Would a complementary weld on the bottom cancel out the upward distortion?
My thinking is that if the weld on top pulls the ends in that direction, a
weld with the same settings on the bottom would tend to pull the ends in the
other direction.

Maybe, but that's above my pay grade. Could you add feet at the ends?

I don't trust my amateur welds in tension like that unless I test
them. When I made scaffolding I applied 1000 Lbs vertically and 500
diagonally to the frames, after grinding the welds smooth so cracks
would show up better.
