For your consideration....
Fewer leagues makes it easier to run...but not sure if consolidating all into fewer leagues isn't more work right now. And it looks like it would only be 1 less league. Probably not worth the effort.
Right now, there are 53 people taking a total of 72 teams. 19 people are in more than 1 league -- 4 in 3 leagues (Bass, BroncoFreak, crippler, ryheaps) and 11 in 2 leagues (bro1ncos, cobalt, genester, Go DC, Jason Wood, JeremyX13, jhexel, Maggot Brain, Stinkin' Ref, Biabreakable and Anarchy/David).
To get up to the 80 teams needed for 5 leagues, 8 more people need to double/triple up. I'd start with those in the fewest leagues and work up from there.
