Hence the reason I did not go with a riser (yet). Have to put it right under the frame unless you want to make the track bar really short.
I'd put a big gusset on that lower bend, should be enough space that you won't hurt uptravel at all. Speaking of which, did you cycle suspension and see if you even need the lower bend, maybe the tire will hit way before a straight track bar on that end will hit the frame?? At the very least I would figure out exactly how high you can go and put the minimum bend needed on the lower end. Same for the upper end. Otherwise, it's been done (Z-bars) for a million years on steering systems, but ain't legal anywhere in jersey, thats for sure.
