Normally I'd gently angle ground round a brick to remove it, how can I get the job done in this case? The downpipe is cast iron and can't be left disconected.

You have a serious problem there.
What you need is "stitching bars"
You chisel out the pointing and glue/cement the stitching bars in across the crack.
You can get behind the pipe with a seaming chisel no problem.
You can get hand chisels or SDS chisels.

I had a crack down one wall. Although I knew it was no problem (it
wasn't moving and was obviously settlement shortly after the extension
was built rather than subsidence), I was moving my mortgage and the
valuer wasn't happy with it. I had to pay for a structural engineer to
look at it, who agreed with me, asked if it had moved while I had lived
there and said that my knowledge of it over time was of more use than
his inspection. Anyway, he recommended (more to keep them happy than
anything) that whenever the room affected was being decorated next, just
to stick some thin rebar in the mortar lines, across the crack and epoxy
mortar it in.
