Not to go too far off-topic...but thwt us essentially what the upcoming Plotweaver system from Brotherwise Games is doing, starting with the Stormlight Archives RPG (with Mistborn and generic Fantasy versions in the pipeline): basically takes the 5E Skill system and it's math, and makes everything in the game work that way, Spells and weapons included.uses skills in place of most other character abilities so that any action is a skill check. Weapon groups and spell schools are skills, etc.
A setting built with the assumptions of 5e at its foundation (Radiant Citadel is close, but doesn't lean into it)
New, modern, hero to super-hero journeys from its origins as opposed to most of the old settings starting with zero.
