Thanks! That would be a welcome addition.

Are the fonts you have in mind shipped with LuaTeX distribution?

Adding Timothy to CC. His WIP conditional preamble branch looks suitable
to add the proposed functionality.
What will happen if LuaTeX is not installed on the system?
Also, just to double check, is LuaTeX fully compatible to LaTeX? That
is, if we have an existing org file using LaTeX-specific commands and
packages, will it work with LuaTeX?
