I would like a Space Mercenaries! spin-off.
No way would this group even remotely get along! But by the Myrka’s not yet dried paint would that be half the fun of it 
Sounds like Doctor Who’s suicide squad. I think Captain John should also be in the running.
Then we have got to have a Peter Capaldi cameo as whichever villain he played in that movie 
Captain John? Sure! He fits the bill perfectly
Roll for Insight
We follow Rogue during his early years before he met the Doctor.
Catching monsters, getting into scrapes. Meeting handsome strangers.
(Could also have a series after, where he is trying to find a way out and to meet the Doctor again)
Into the Jackieverse
Jackie is helping Rose with her Dimension Canon before it has been finalised - she has a part-time job cleaning the equipment. She is trying to dust the machine she accidentally presses some switches - boom, Jackie is sent flying into different alternate universes!
A bit like Quantum Leap, Jackie swaps places with people throughout different dimensions. Jackie in the War Room of Gallifrey! Brigadier Jackie as head of UNIT during the 70s/80s! Jackie as the companion to the Time Lord known as The Doctor!
Bill and Heather’s Excellent Adventures
I really want more of Pearl Mackie! And while I’d prefer more stories with her and the Doctor, if Capaldi doesn’t want to do any more then this is the next best thing! Plus, the more lesbian space adventures the better!
Yes! (Also read the novelisation )
NooooOoOOOoooooOo! 
Bill yes! Deus ex Machina Space Puddle Girlfriend no!
God how did I not think about Bill!!
I’d also like more Martha but after hearing that her box set is kinda meh I haven’t bothered to investigate it.
If they ever do more Tenth Doctor Adventures boxsets, then they need to do a Ten/Martha set. They’ve already done Ten/Rose and two Ten/Donna, we need to complete the era.
Almost sort of fitting that Martha is left out 
Dissected from the TW Main Range is great!!
(and you did say you wanted more Gwen too!
I’ll get there! I’m listening to all the TW Main Range from the beginning 
Fair, may take you a while then lmao
Definitely wanna hear your thoughts in the TW thread though!!
I wouldn’t mind Big Finish continuing the adventures of various comic and novel companions. Gabby and Cindy, Sam Jones from the EDAs (I really need a voice that’s not Lucie Miller in my head), the continued adventures of Eight and Destrii.
Wait! Bill Filer was right there! You could’ve said Bill Filer! I’m very disappointed now!
I’m going to say Coldstream! The Doctor casually mentioned them in the Doom’s Day event and I want to know more!
Bill Filer is an Agent of UNIT, Washington Division not a Space Mercenary!™
And I am 98% certain that I mentioned a UNIT spinoff with Bill Filer, Corporal Bell, Sergeant Osgood, Ann Traver and probably more in an earlier similar topic
It would be cool to get a series about the Corsair.
Sounds like a good place to have a pilot for the mandatory Frobisher spinoff
Ace and Graham after Power?
Bill and Heather post WEAT/TDF?
Something with the cast of UtL/BtF?
The only one I’d be against would be a Clara spin-off, because I cannot stand Clara.
This needs to happen!
You know, we’ve been talking about Love & Monsters. How about an Elton series?
Obviously, you’ll want Ursula. I feel like he might know Ryan on youtube, which could potentially bring in appearances from Graham and Yaz.
I bet Elton and Ryan would have some conflicts with their musical tastes…
