@Arkandel There is a setting-agnostic, generic version of the Numenera rules (cypher) and a different setting (the strange), so… it’s already not required to be a billion years in the future.
You can fluff up the mechanics in different ways. Force field… I think you mean holy symbol that needs fresh holy water to ward off attacks! Grenade? Alchemical bottle.
… hell, call everything a potion.
The trickiest part is character descriptors. ‘Replaced flesh with Cybernetics’ might not work 1:1 (but maybe clockwork?)
Also also, one of this is to say that there isn’t a corner of the Numenera setting that thinks it is a replica of Ravenloft, everything looks like it exactly, and now a cyborg arrives in a very GURPS fashion.
Edit for spelling and calling the one book by it’s actual name.
