Headcanon

When I get my table back, I plan on introducing my headcanon involving Doctor Whooves, but I want your opinion if it will be too much for the story:

Whenever a Doctor regenerates, the previous Doctor's soul gets sent to Equestria by Faust and given a chance to live a normal life (like no regeneration or extended lifespan) but, since the Doctor will always be who they are, they're each given their versions of the TARDIS to explore all of Equis and beyond.

But, Weeping Angels have followed the Doctors, so from time to time they need to take care of business.

So, what do you think, too much?
