Love the idea. Had a similar idea, the 5e framework with an immense pool of feats, class features, and others. It started to change and then I found your system. I have brought up the idea to my group and most said 'YES" so I'll have some test data soon-ish

Awesome! I'm glad to hear. I've been polishing up the rules a bunch and will have an update soon. Let me know if you come across anything clunky or confusing during your play.
