Seven and Adam.
Thirteen and Leela… and annoyed Yaz.
Three, Barbara and Ian.
Twelve, Missy and Camelon. Missy is annoyed that Cameleon is taking her job.
Twelve and Amy, with Rory constantly saying “What did you say?”
Six and X-mas speccial Donna. Ear plugs required.
Ian, Barbara and ten could be fun.
(I’d actually thought of 6 & Tegan, but went with Leela because 6 had met Tegan, and Leela’d also be fun…)
Ten and Frobisher - Make it in the CG animated episodes.
Two (late era) and Jack - The tension between Jack and Jamie would be great. Now Two as a second fighter to work with.
Seven and Kate - Seven being more devious is the way he deals with UNIT and trying to prevent them getting too big for their boots, while still trying to mentor the Lethbridge-Stuart line.
Thirteen and Susan - Grandma Doctor. It’d just be emotional.
Fourteen and Adric - Just really layer on the trauma.
War and Jack - Jack would make a perfect soldier for the war.
Nine and Sara Kingdom - They could soften eachother.
One and Romana - I just feel like there’d be a really interesting dynamic
Two and Frobisher - They’d have fun
Three and Jack - Two action men
Four and Evelyn - idk I just feel like they’d really sparkle off each other
Five and Jamie - I just picture Five getting exasperated
Six and Ace - Six is very much a therapist-type character. I feel like that would be an interesting dynamic.
Seven and Clara - They’d bring out the worst in each other
Eight and Chris and Roz - I know that there’s just a really interesting dynamic here I’d like to see.
War and Lucie - The drama would be palpable between these two.
Nine and Evelyn - She would fix him
Ten and Jamie - They’d just have so much fun. I genuinely think that Ten works best separated from the trauma of Rose and there wouldn’t be a chance for him to be faced with that trauma.
Eleven and Ace - She’d be so angry about the reveal of his more manipulative side and I’d like to see that.
Twelve and Leela - Specifically a post-Time War Leela.
Thirteen and River - Wives
Fourteen and Susan - I see a lot of healing taking place.
Fifteen and Jo - She’d see so much of her Doctor in him and they’d be absolutely adorable together.
I approve of your message.
But we need - Tegan (Mara Possessed Variant).
Nine and Barbara
When I feel like drawing and don’t know what to draw I tend to randomize companions and doctors to each other and draw them together, those two I had recently and I kind of think that would work.
They would be so good together. 100% Barbarine 
I believe you forgot to mention Tegan there…
How could I forget about Tegan 
Brave heart BillFiler!
Totally agree with that.
and Tegan and Donna with 10
That would be a hoot.
Ace with Capaldi or 11
Ace and Elven would be bonkers!
I would love to see Sam Jones and 12 together. I think they would get along great
This list but with Nyssa as well
Ok… another…
Leela and 15
LEELA: But we have to kill it Doctor
15: No wait… think about giving it love instead. Maybe a hug.
15: Unless it is Undead, then kill away babes! Death + Death equals Life! Apparently…
I think 9 and Molly could be an interesting dynamic, considering how good she was with traumatised soldiers.
Adric & 6. Just watch the sparks fly lol
