It could be that the SU... universe and Ooo either exist in the same multiverse, and/or are parallel versions of each other. In the AT episode "Evergreen", it's established that a certain comet reincarnates every millenium, taking on a different form. In AT, the comet took on the form of a green, life-destroying meteor. It's possible that, in an alternate tineline, the "comet" took the form of the Homeworld invasion instead.

It's also interesting to note that Grob Gob Glob Grod, a god-like figure in AT, strongly resembles a Gem- a Fusion, to be exact:

The shape of their head is attributed to headgear to cover up baldness, but the rest of their body still has a vaguely Gem-like appearance, and we also know through Jasper that it's conceivable for Gems to be able to manifest headgear.

Also, in AT, Gunther lays an egg that hatches into a pink kitten that can shoot lazers:

Perhaps an alternate version/relative of Lion?

Now, of course, none of these connections are really solid, nor were they in all probability intentional. Still, it's interesting to consider.
