corner bending for art panels - is this possible??

I posted this earlier in a different part of cnczone but i think here is more relevant

Hi!
hoping someone out there has the solution to this...

I am ideally trying to create panels out of 2mm Ali with mitered corners and 1in flanges bent to 135 degrees - to eventually send to a cnc bending fabricator.
- Are the following corners possible to fabricate (see panels in red and blue example)? I know drawing it in CAD is one thing...
- or do i have to offset one of the bends (like in the green example)?

cheers for any advice you might have!!
