What if Paramount Global co-owned Columbia and TriStar?

Inspiration came from this idea and the Disney/Fox merger.

We all know that ViacomCBS has succeeded Viacom and CBS Corporation, and that Sony Pictures is... well, Sony Pictures. But what if its divisions and subsidiaries were thrown into ViacomCBS' table?
