Blackpink members could handle a solo tour on arenas?

We all know that blackpink (as a group) is popular enough to play in stadiums as we've seen in born pink tour, and the members also have their solo hits and dozens of millions of followers on ig

Its not happening for now since blackpink will be touring together this year, but, if today the members announced solo tours on their own (like jhope and suga), their demand is enough to what kind of venues? could they fill up 10k~15k arenas, even more or even less?
