If you look at it and take top bar and cut and fit it in the bottom bar, you would gain a deeper loop, plus a extension for a better look.
You can also maybe fit 26x2.35 tires in it. Print some shots and photo chop, just make sure you sleeve the frame with rosette welds and alignment jig to keep it all straight.
It has been done before in some older builds, but all takes time even looking through old builds. Something like this you have to know what engine you want and have it all planed out, and even have a quicky build to ride and resell while you are building. .............Curt
