Since you have a press brake, you're golden. Butting two dies together to get full length has been done forever, but they are usually the same profile. I take it the inside V is narrower, not just the outside. Can you rake the top punch frame to account for the slightly narrower section?

On edit, I left out some info in my first post. Changes are in italics.

1.5" die = .75 between bends on the small end

8*pi = 25.132
25.132/.75 = 33.5 bends

So call it 32 bends
360/32 = 11.25 degrees/bend

25.132/32 = .7854 between bends
