1970 Duster, Trans-Am-inspired "Pro Touring" build
Keeping with one year/make/model would be great in my opinion.
I do have a Viper brake kit from Cass for my Valiant that’s in chassis shop hell. That kit is way overpriced, IMO, and uses a rotor that only Cass sells. With Vlad’s way you can get rotors from NAPA or Amazon!
This way looks more economical and you could stay with one specific donor for calipers and rotors, purchase some Dr Diff hubs, and Vlads brackets.
