Fictional crossovers between characters on television shows have been going on for a long time – often used as a way to offer cross promotion between shows.  Mad About You and Friends had a great crossover (Including a long running one involving side character ditzy waitress Ursula Buffay played by Lisa Kudrow), Cougar Town characters Jules Cobb and Ellie Torres (Courteney Cox and Christa Miller) appeared in Private Practice, Ally McBeal and The Practice (Two of David E Kelley’s biggest hits) often crossed paths too.

What about the crossovers that would never happen, but could be pretty awesome?  Characters that are no longer around, brought back to life, currently underused characters getting more screen time in another show…check out my ‘crossover wish list!’

Easily said, Aunt Jackie (Laurie Metcalf) was one of the best bits about Roseanne.  She was somewhat crazy, highly lovable and suffered through some rather tough situations and when we last saw Jackie, it was revealed she was in fact a lesbian.  I could easily see her Jackie popping up in Modern Family,  fitting in for a guest spot quite perfectly with her hilarious antics with Cam and Mitchell – as long as she is wearing that bitchin’ knitted sweater!

What could be better than bringing in two paranormal investigators to the town of Bon Temps where vampires, werewolves, shape shifters, faeries and witches all run rampant?  While the True Blood gang live in a world where Vampers are an everyday and (somewhat) accepted minority group, faeries and shifters and werewolves remain relatively unknown to humans, which could be the perfect reason to bring our FBI agents Mulder (David Duchovny) and Scully (Gillian Anderson) in to investigate!

Who’s to say, that after Weeds left our screens, the world Nancy Botwin (Mary Louise-Parker) knew and lived in went the same as that of The Walking Dead?  Nancy would be the perfect replacement for the recently deceased Lori (she’s certainly less annoying) and we know she’d happily take her withdrawals from iced caffeine drinks out on the walkers.  Add in a romance with Rick Grimes (Andrew Lincoln) and we have ourselves a crossover!

Pretty Little Liars features secrets, murders, blackmail, lesbians, teenage sex…it’s the modern day Dawsons Creek which would be a perfect launchpad to bring former creeker Jack McPhee (Kerr Smith) back to our screens.  No stranger to secrets, McPhee spent his first few seasons hiding his homosexuality from his friends.  Granted Jack would now be somewhat older than the main cast, so i’m thinking in a teaching role, perhaps, with more secrets of his own, with extended screen time with Caleb or Ezra or Toby.

There’s no denying that since O’Hara (Eve Best) packed up her wardrobe and stethoscope (and new baby) and headed back to London, Nurse Jackie hasn’t been the same.  The same could be said about Greys Anatomy withAddison Montgomery (Kate Walsh) leaving (for the dreadfully boring Private Practice).  The team at Grey-Sloan Memorial are in desperate need of that kick-ass surgeon who looks fabulous in expensive clothing all while thinking about which 5 star restaurant she’ll be dining at for lunch.  The only issue here – we doubt O’Hara would be seen dead in Seattle.

In total, Sydney Andrews (Laura Leighton) has been killed off twice during Melrose Place’s run.  What’s to say, she can’t be brought back to life for a third chance at life?  She’s highly skilled in bed-hopping, blackmail and bitching, all skills needed to fit in perfectly with Emily Thorne and the Graysons up in the Hamptons.  Let’s just hope this time she wouldn’t end up over the roof of a car or face down in a swimming pool.
