Replying to your PM as well...

If you want perfect gloves, bring them both via Transformer as Type: "Cloth", Skin Template: "Use Original"
Convert to Accessory (bake current shape), then select Both (right and left) and Modify > Merge Accessory from menu.
Consolidate materials and apply normal and roughness maps.
Transfer Skin Weight > Other
Transfer Skin Weight > Gloves
Make sure to mind the order, first Type: Other and then Type: Gloves
Edit Mode > Sculpt > Mirror mode > Pull Brush. Single pass over the gloves top to fix the poke.
DO NOT use Conform. It messes up gloves mesh.
Hide Mesh Tool  > Advanced mode > Mirror select > Select arm partitions up to the first part of upper arm.

One more tip. Before converting to accessory, stretch fingers (I did not even use a T-pose).



But you still might need to fine tune skin weights for particular character until polygons are evenly distributed.
