How to specify other SVG conversion tools (Inkscape) into the chain

Discussed in #1140

I'm using SVG a lot in my markdown, and it renders nicely (most of the time) in PDF by way of rsvg-convert part of the LaTeX chain:

(rsvg-convert.exe:2516): Pango-WARNING **: couldn't load font "Helvetica Not-Rotated 13.640625", falling back to "Sans Not-Rotated 13.640625", expect ugly output.

I'd like to use Inkscape instead, as it does some things better, especially with fonts I've installed in Windows.

Is there a way to specify that SVG conversions to PDF should be done using Inkscape?

Probably related to #997 where rsvg-convert was mentioned, as Pandoc is using it directly when PDF writer is used: https://github.com/jgm/pandoc/blob/b263f383040618ff991912512ccd396b83d43da5/src/Text/Pandoc/PDF.hs#L194-L205

#997 and this issue are probably about a Lua filter to do the same task (SVG converion), and which would be configurable
