Is there any way to disable the sub theme or to use another sub's theme for this one?

I'm not really into this sub's theme and it doesn't appear to be changing, so I'm wondering if there's any way to switch it off or switch to another's theme for this one (for example, using r/rpdrtearanny's theme as a custom skin for this one, or even making my own custom skin to use?)

EDIT: WOW, r/rpdrtearanny just banned me "for plugging their sub" lmfao. That's sad. I guess every fandom needs its hipsters.
