I think it's safe to say PJ really wants to do it.
That's a pretty old picture. (I still want to see one of him in the original 7th Doctor costume he owns, that he wears to play DW with his kids in.)
And there's a big gulf between "wants to do it" and "has commitments to massive movie franchise until the end of next year".
