Sure, I'm happy to replace macros with templates where possible.

If possible, I'd rather avoid too many cute tricks.

Yes, like many other things in Octave that are not "modern".  When I
started writing Octave, C++ did not have a template mechanism at all,
so I used macros.  Single precision arrays did not seem important back
then, and when they were added, David Bateman thought it would be
easier to copy code rather than use templates (at least that is what I
remember).

If you can clean things up and eliminate some cruft, that's great.
But I would appreciate small patches that fix one (or just a few)
thing(s) at a time as that is easier to follow and makes debugging
easier if you happen to make a mistake and a bug is discovered later.
