I have some scripts for doing projected radius profiles using projections and FRBs.  They'll certainly be different from the Profile1D stuff, but they work OK.  I'm happy to share them if you want a starter for this avenue.

I believe this is what has been done in the past -- Sam wrote a set of
scripts that did it this way.  I think, though, that you might be able
to use the cylindrical radius derived fields and then accumulate
within them.  Would that get to where you want the analysis?
