Random question:
Since you're obviously a great fabricator, have you put any thoughts into changing the tank or perhaps making some indentations in the sides of this tank for your knees? It might make the bike more comfortable to ride in the full tuck position you'll be adopting with clip-ons.
Since making suggestions without solutions is kinda lame, I'll offer up this idea. What about running a Benelli Mohave gas tank?
I think it would compliment this frame design very nicely. They're not cheap but here is a link to one of the lower costs ones I've found.

I used one of these tanks on a cafe racer build I did a long time ago with a CB350 and it really changed the look of the bike for the better. It's a rad shape.
Even if you don't want to, the bike looks great. I can't wait to see the finished product.
