Back in the days where safety management was a rude phrase we used to do it all the time. I certainly recall doing a talkdown on a Britannia 737 which had failed to get in on a Cat I ILS. We offered him a PAR and successfully took him a 'little below' the procedure minima.
The real art with CR62 servo and gain was keeping radar contact on multiple aircraft on a 3-4nm stream with one controller servoing not only for himself but for the second talkdown man. Then again, I could bore you with stories about the SLA3C.......
