Is it kosher to include some of the segments that were PSA-like aired as fillers with some shorter cartoons? Some Schoolhouse Rock stuff was aired like that. And Time for Timer and similar bits.

I'm coming up a little short in some spots and not sure I want to fill ALL the time with commercials or short PSAs.

I'm thinking a little Conjunction Junction, Pronouns, or I'm Just a Bill tossed in occasionally. They're about three minutes.
