Converting hands to gloves HELP?

I'm a big fan of World of Warcraft and wanted to make my characters in Sims 4, however the issue is that my character in question is a troll. Trolls have two fingers instead of four on each hand (not including thumbs of course) so I wanted to convert their hands to a glove for the game.

There are issues with this, such as how am I going to match it to every skin tone, just like people do with the elf ears accessories? I know that if I add on the hands, it will still show the texture for four fingers upon two fingers.

I am used to using 2.70 and for the model exports I have only recently gotten 3.60 for compatibility, and although the interface is easier on the eyes, it is far more confusing and I don't really know what I'm doing for the most part. And the hand itself that I exported from WoW is posed differently, so I don't know if I need to position it to the hand so that the movements of the hands don't look weird.

Essentially, I want these gloves to replace the hands, be fully functional as hands, go in the gloves category, and match to the skin UV map.

Another question I have, will deleting the hands in the rig that comes with exporting the ts4 mesh remove the hands in the gloves mesh?

I can't figure out how to upload the image to show what I want to create, so all I can do for now is write these questions.

Thank you for any help that can be provided!
