It's not going to happen, sadly. But - if you aren't aware of Raising Hope, or at least aware of it's connection to MNIE - it's designed to sort of be a spin-off. It's made by the same guy, and the family in the show live either in Camden or the town next to it (haven't watched it in awhile) and it features a LOT of the people from Earl (in different roles, I believe.)
Actually, I should start watching Raising Hope again...
