I don't think it's possible, Terra Luna probably won't be able to continue unless they create new tokens, but from the cases that have happened, it will make the founders of Luna criticized by many people and will probably have a hard time getting investors again, I'm sure they've been too disappointed with the founder of Luna and will never provide support again.
there is news regarding the snapshot regarding the Luna holder. it's a related update from Terra 2.0 team. I'm not sure it will go smoothly. because this news is still uncertain.
although the developer's efforts to pay for their mistakes are currently quite harsh. it will still be difficult to restore investor confidence. This can be used only to get airdrops and then leave the project.
I think it will be difficult for Luna to return everything they have achieved before they destroyed themselves.
