F9 is big enough to launch a reusable laser thermal space tug in one go, if the laser array is on the ground. This design estimates 3000s Isp for LH2, so call it 2250s for LCH4, which means if you make that switch and scale it up to work with Starship for launch and depot you can do crazy things with it

So it's a single aerospiked RL10 using the heatshield for regen cooling? That first stage is going to need to do a LOT of work, which will make reentry spicier.
