MoPar Brake Upgrade Options?

Hello everyone! This is my first forum post (besides my introduction), and I really just have a question for you all. I've done a lot of research about what's available out there for bolt on front brake upgrades, and it looks like there's:
  1. the B/E body upgrade for drum cars
  2. the KH 4 pot upgrade (seen this on a some vintage racers)
  3. and a few different Wilwood kits ranging from $650-$1000.
I actually have the B/E kit for my 64 Cuda, and boy are they heavy! The KH calipers seem like a solid upgrade from the big single pistons, but it's still older tech. And the Wilwoods can be expensive.

As a community, how would a cheaper 4 pot brake upgrade that still fits behind 15" wheels be received? The upgraded parts, aside from the hub and caliper bracket (which would essentially be the whole kit), could all be sourced from any national auto-parts store, would be relatively cheap, have a substantial aftermarket support network in place for easy further upgrades, and be on par with Wilwood kits in performance. IF this package existed, would anyone be interested in it, or are most happy with the current options? Also, if this kit already exists please point me in that direction!
