Recent -- i.e. 2017 -- consensus favours keeping the articles separate. It is our general desire to do this with entities that have different forms over time. Also, any film that might have starred K9 doesn't seem as certain in 2017 and it was in 2015, so a great deal of the urgency has been taken out of the OP's proposal. At this distance from the original question, there appears to be no K9 Mark 3 forthcoming anytime soon. Even if new K9 adventures do come out, however, there is no consensus in the thread towards the OP's proposal.

Note, too, that the Master isn't analogous to K9, as there are several different iterations of the Master that aren't regenerations. The Ainley Master is the same guy as the Beevers Master with no intervening regeneration. The modern K9, by contrast, regenerates, while the BBC original K9s are physically distinct units -- completely separate builds.

Result: No change. Start new articles for each incarnation of K9, as with the Doctor.
