Stock clutch mods?

I’ve never used an aftermarket clutch. I have modified the stock clutch, clocking the secondary, changing rollers, and on my Wildcat changing the clutch spacer.
My question is can I modify the stock clutch on my xp1k 4 for lower engagement rpm? I have to drive one footed and I need a good creep speed for loading and crawling.
If I have to use a clutch kit which one would work best for my application?

Thanks
Dwight
