Not bad at all, joel. Rumblers, we are, and happy to be so!
What's bad is you haven't shown us a pic of your Rumble 200 yet and picked up your officialClub number! Come on. We wanna see!

Yes, as
@dbbltime said, you are correct, sir. Most any 8 ohm cab should work OK,
if it can handle the up to 100-watts continuous that your R200c can put into it (or if you keep the volume down, if not)
Now, that's not to say that other brands will sound as good as the Rumble cabs that were actually
designed to work best with Rumble amps and combos. But they should work OK.

Yes, SB, a 16 ohm cab would be electrically acceptable to use, since it is above the 8 ohm minimum. But, it probably won't give the full extra power that an 8 ohm cab would!
That is, just like the R500c built-in 8 ohm cab gives only 70%, or 350-watts max, of the amp's 500-watt potential, the 16 ohm cab may only give some similar percentage of the extra 150-watt potential, for example, perhaps only about ~100-watts(+/-), and may even reduce the power to the internal cab, say ~50-watts(+/-) for a total of just ~400-watts(+/-), which may amount to an imperceptible difference. [
Swag figures! There's prob'ly a way to calculate a closer estimation, but I'm not familiar with it] At any rate, the 16 ohm external cab would produce a lot less power than the 8 ohm internal cab! If that is acceptable to you, then go for it!
