Does anyone else do this for Doctor Who too?

I'm curious if anyone else would do this whenever a new doctor appeared on screen? For me, I would usually do this upon my first or second rewatch, but I love watching series 2 for example and imagining Christopher Eccelston in the role. Same with series 5 and David Tennant, series 8 with Matt Smith.

Now, obviously, certain episodes are harder to convince oneself that they could be pulled off like regeneration episodes, but the filler episodes are usually such a fun "what if" scenario.

Does anybody else do that??
