I'd prefer to have another regular season first. But if they do a special winter season all-stars 2 season then that'd be okay, cause we'd still get a regular season next summer.
Your idea of having an international BB all-stars season with BBUSA rules is good, but i don't think it's possible because i don't think you're allowed to work on a temporary visa in the US, and because they pay you to be in the BBUSA house(they have to because of state laws) i think being on big brother counts as "working". So unfortunately i think that's impossible.
