Call me crazy, but maybe a network like The CW or My Network TV could air EI programming in primetime. I recommend Saturday nights 'cause it's usually for the most part repeats...
Okay, I'll call you crazy.
Seriously, what makes you think that CW and MNTV stations would particularly care to give up two hours of prime time in order to carry national programming that contains advertising inventory that's of pretty much no value to those stations? The thing that has killed childrens' programming on broadcast TV -- period -- is that there is no market at the station level for advertising within childrens' shows. So the only way this stuff is viable is if it attracts adult viewers in significant numbers, which I don't see happening with much of any of the EI programming that's been produced so far.
