I may be spitting in the wind here, but....I think a lot of people--particularly new players--would appreciate another league option. Call it a nonwinners league or a rookie league, something for those with a limited number--or zero--championships. Let's face it, every open league is about 75% Hall of Famers with dozens of championships and thousands of games experience. A newbie tries an open league, gets crushed, and after a few attempts gives up the game. I can't imagine you guys at WIS are making any money on this particular game--all those multi-championship guys are playing for free, right? An open rookie league would make the game a lot more competitive for a lot of players.
P.S., Yeah, I understand that anyone can start a theme league with those conditions...except it would probably take about a year to fill one!
