Wow! A 12" rise is a lot for a bomber! With the adjustable risers pictured the max is 6.5", so if you modified their design you would have to use 8" angle sections and I can't see those looking very cool (or being real stable). If bomber seats are your choice and channeling is not in your plan seems to me you are left with making a "box" about 8" high, smoothing the corners and edges, and carpeting it, then use the risers that 406Rich suggests; or just make your box 12" and mount direct. Do you need front to back adjustment for driver's of different height? Maybe a different style seat that has more section height in the bottom would be a better choice? Like buckets out of a mid-60's muscle car or t-bird or ??? I think it is going to be hard to get the right "look" with bomber style seats, given the seat height criteria you have outlined, but that is just my $0.02 and seat selection is a personal thing.
