Time lords can’t do anything, they’re all dead (twice now, thanks RTD)
Maybe the doctor could take you back there with a TARDIS, but time paradoxes and fixed points in time and all that
Given how many times they've been gone forever, never to come back, and then come back again, I wouldn't count on them being dead for long
