Has anyone removed their brake booster and ran dual side by side brake master cylinders?

I am trying to locate a suitable front and rear master cylinder to push Toyota 4x4 calipers in the front and 1989 vintage 240sx rear calipers in the rear.

Thanks,

This is the only setup I have seen specifically for Z's.

John can also help with advice on this I'm sure.
