Are there any decent estimates for the maximum amount of mass Starship could bring up AND down?

Obviously the plan with Starship V3 is for it to be able to bring 100 tons up to LEO, then return with no mass, however if it had to bring up the same amount of mass that it brings down (for instance in some kind of mass human transport system to LEO, or for LEO manufacturing), what would it's maximum payload be? In theory it would result in needing a stronger landing burn, as well as having a higher terminal velocity when coming in for a landing. Would that be a particularly large amount of fuel even? Could it even handle reentry with a bunch of extra mass?

What happened with LEET-1337?

Was just browsing the wikipedia and it got mentioned, seems that it was meant to completely replace Raptor at some point. All the articles on it though are from 2023, so is it just dead? Have all the ideas that could've gone into it been transferred to Raptor 3? What would it have even been, it sounds like raptor 3 already basically got completely reworked between versions, so was the plan for it to be some kind of crazy new engine cycle? I don't think theres really much room beyond FFSC, unless they planned on doing like an RDE or aerospike.

EDIT: Because apparently nobody knows what I'm talking about, here's a link to the wikipedia page on it, and you can look it up and find old reddit posts from like 2 years discussing it https://en.wikipedia.org/wiki/SpaceX_Raptor#LEET
