I would usually be sad to see another original RPG go 5e compatible but Neuroshima was infamously poorly designed ruleset, possibly worse than Shadowrun. I probably won't be running it, but may steal statblocks for my 5e game if I need weird stuff again.
The thing about D&D is that there is literally zero way WoTC can actually stop you from creating 5e content without their license. You'll have a hell of a time publishing it, but there's basically nothing they can so to stop you from just printing sheets or installing a dice bot on discord and getting to the races.
And they also dual-licensed most of the 5e SRD under Creative Commons as part of the "oh crap we didn't expect everyone to be mad enough to actually hurt our bottom line" drawback from the OGL debacle.
Legally, they can't keep you from publishing 5e content. You can even publish the 5e rules in their entirety so long as you change all the wording and pictures. I think they can keep you from publishing stuff involving their settings and characters, but you can still use their system.
Legally, they can't send the Pinkertons to rob you, either.
