Hey Don! I think you have enough extra Bed Rails (tubing) to make some COOL wheelie-bars !! Come on Don .... Do It !!
And just an observation (suggestion) the TORQUE that will exist in the BB shell you have mounted using 2 frame tubes MIGHT need more (extra) stiffening tubing rails (4 total) ...... OR a "plate gusset" BMX-style around the BB shell ..... I just know the massive muscles in your legs COULD possibly twist that BB where it is located without more stiffening/support .... the Torque you generate will be STRONG ..... just my 3 cents worth
CHEERS !! CCR Dave
