a rad bleed valve is knacked & it's on one of those rads where

What are the odds of successfully drilling & tapping a new bleed
valve into the rad? Or is it time for a new "normal" rad? Or
something else?

Mum and Dad had one with the flats rounded off, and the bleed valve was
(annoyingly) facing the wall, so you couldn't even try to get the
pointy-nosed pliers in. But new radiators don't cost much nowadays.
