quick hypothetical for yall

if you could have a doctor dominate the series for the rest of the whole future run time, who would it be? this is a bit of a different question then just "WhO iS yA FaV?" bc ALLLLL of the doctors have different vibes and writers to them, they have their own respective adventures that give separate story tellings. ex: 9/10 is like a love story but some more classic adventures like 1/2 were just silly goofballs who were just doing their own thang. plus the dynamics between companions are  drastically different with each doctor. but anyways if you could choose one dynamic duo/trio/fam to dominate the series, time being no object, who would you pick?
