Sugar has confirmed that the gems we know as fusions have single-gem equivalents on Homeworld…

And you know what? 

THAT MAKES THE FUSIONS 10X MORE INTERESTING TO ME.

EXAMPLES:

Smoky Quartz – A homeworld version of Smoky would look nothing like the one we know. Steven looks like a human (duh), and Amethyst is defective. So a Homeworld version? The only thing in common would be the color, probably. A regular Rose Quartz and Amethyst would make a giant, beefy powerhouse… not the round, cute, (somewhat) short and fun-loving Smoky we know.

Opal – Again, Amethyst is defective. So, right off the bat, you loose a lot of the size and shape that a “normal” Amethyst has. Pearl? I sincerely doubt Pearls are even allowed to fuse on Homeworld.

Garnet – Two gems from different classes fusing together is a big homeworld NO-NO, so a Homeworld Garnet would, again, look nothing like the one we know.

So basically, no matter what fusion you take, they’re all incredibly unique compared to their Homeworld counterparts… because each Crystal Gem is incredibly unique compared to the rest of Homeworld.

Also, this means your OCs are canon until proven otherwise. lolz
