Boolean+Zremesh while preserving polygroup shape?

I’m trying to merge these brown and yellow subtools (pic 1) into a water-tight mesh while preserving polygroups so I can separate their UV’s.

I booleaned them (pic 2 left) but since my mesh is so large, zremeshing on highest settings (pic 2 right) lost a lot of details.

Starting to wonder if my workflow is wrong? Typically I’d bake color ID but that’s not an option.
