I could see anyone 3D printing older style miniatures could just scale them up. I’ve done this for terrain pieces and conversion bitz to get the scale I wanted. I haven’t seen anyone doing this with Chaos Dwarf models… but it would be a welcome comparison to see how well it works!
For “inspired by” there are a number of newer helm models that are probably a bit bigger. I know Paimon Miniature’s were on the big side, I’d guess Knightmare’s are too
