D&D 5E (2014) System overhaul, seeking similar projects

[Nevvur]

I've been working on a 5e overhaul that removes spellcasters, expands combat options, and implements an "Epic 6" style of level progression. I'm looking for any existing projects/publications based on SRD5 which share one or more of these qualities. Mostly, I want to see how other people are handling them in order to make possible revisions to my own system.
