Veronica Mars, FBI?

Some people have been asking what I know about this Hollywood Reporter story about "Veronica Mars" doing a time jump to season four so that Veronica will be training at the FBI Academy in Quantico.

Getting details on this one has been hard, because no one wants to talk on the record, and Rob won't talk about it period, but here's what little I've been able to gather:

• If this happens, Veronica won't be studying at the FBI Academy; she'll be a rookie agent.
• All of the actors are still signed for next season, though I can't imagine all -- or even most, or maybe even anybody save Kristen Bell and maybe Jason Dohring -- surviving into the new format, unless Veronica gets assigned to the FBI's Neptune office. (Logan's rich and has nothing better to do than follow Veronica from place to place, assuming they ever get back together.)
  
• The comparative success of the Pussycat Dolls show has made the chances of "Veronica Mars" returning in its current incarnation all but impossible. On the other hand, I know at least one decision-maker at the CW who's intrigued by the possible new format, and everyone there wants to stay in business with Kristen if they can.
  

So that's what I've got. Now three questions for you, my little research monkeys:

• What shows have done a significant mid-series time jump? So far, I've got "Alias," "Galactica" and "Wonder Woman" (which shifted from WWII to the '70s between seasons). I don't count a show that just did a time jump for the finale, like most of the "Trek" spin-offs.
  
• What shows have been successful after so thoroughly changing their premise? I guess if you count "All in the Family" and "Archie Bunker's Place" as one show, that counts, which leads me to...
• If the CW decides they want a new title -- under the theory that new viewers aren't going to come to a fourth year show, even one that's been totally revamped -- what would you call the new show? And I'll pre-empt all the "Silence of the Lamb" suggestions right now. RIP, Lamb.
  

Fire away.
