Think about it, could the Tardis have the ability to transform into robot mode?

A friend and I were discussing Cosmos and Astrotrain earlier this evening, and I mentioned they must utilize Timelord technology.
This started a discussion about a TF taking the altmode of a TARDIS.

Though, I personally feel it would be much more interesting for "Sexy" to become a transformer. She's already sentient, already alive, and even has a chamelion circuit (Though stuck it may be).
So... according to wonky TF fiction, all she needs is a transformation cog to gain a robot mode.
She's said that she can archive consols and events that haven't happened yet, and even the Doctor didn't fully understand how she could do that. So... if she aquires a TF cog at any point in the future... could she even now be a transformer?
