How would you feel about a spinoff series to the Sopranos, focusing on the earlier years?

Personally, I have really enjoyed Tony's flashbacks to his childhood. It was really interesting to see Johnny Boy and Uncle Junior in action especially getting money out of people. I would like to see more about how Johnny Boy and Junior became respected guys, got made and had their own crews. More details about the rivalry between the two brothers would be really interesting. It would also be good to see Tony making his bones, Jackie Aprile Snr, Silvio, Ralphie, Pussy in his days as a cat burglar and of course Paulie starting to whack guys thirty years ago!

How would you feel about this idea? Which characters would you like to see and what would you like to see them doing?

Personally, I was really impressed by the actors who played the young Johnny Boy and Junior. It would be good to see more of them.
