Brake setup questions

[Bladed Poptart]

Hello everyone, this is my first time posting on a forum. I am wondering if anybody has done tt supra front calipers on the front, and moved the stock sc400 front calipers to the rear. My rear caliper seized up and I was looking at buying remanufactured tt supra calipers all around, but the rear calipers are absurdly high in price for some reason no matter where I look. So I started looking at different caliper options, ls400, supra, remanufactured sc, etc. But maybe this could be a new setup unless somebody else has already thought of this before (which I have a feeling somebody did). Thanks for the help in advance.
