For what it's worth, my two cents on the number of kits/variations,
I love them all, I genuinely think each kit looks great, that being said,
If this set DOESN'T go through Massdrop, you might have a REALLY hard time making MOQ's for each kit, to a point where you will be selling at the bare minimum MOQ which means higher prices which in turn may shoo away many of the people who say they were in for said kits.
Just be careful to not throw provide TOO many alternate/weirdo options, as not having the reach of massdrop can really hamper hitting MOQ
