Raptor 2

Thanks to the NOAA, there's no Starship launch comin' soon, so the Starship-rated tiles aren't being tested. But SpaceX isn't sleeping: they're barrelling ahead on Raptor 2 (230 tons) and on the mass-production effort related.

The Falcon Heavy is permitted for takeoff in the Rio Bravo Delta. So maybe they can use or at least test Raptor 2 with that. It's not SuperHeavy+Starship but it might add some I_sp and knock off some mass-ratio from the vanilla satellites. Might even sell some to the Guianas.

[UPDATE 7/20: Pity there aren't any Falcon Heavy missions.]

On these rockets generally, I learn that many of these rockets use helium. That's to keep the pressure on, so the LOX and L-methane stay air liquide. There's yet another factor of complexity. I suppose that's why "rocket science" is a popular idiom; it's certainly not because M_wet/M_dry = Exp(δV/v_e) is haaahd.
