I tried this way, but:
after changing
Encoding const & BufferParams::encoding() const
to expect the "flavor" as argument, I started changing the 18+ calls to
params.encoding() realizing that in most cases the "flavor" is not (yet)
known:

and runparams is an instance of OutputParams and instantiating
OutputParams requires passing the encoding - so we have a "hen and egg"
problem!

I tried to implement this, but the export buttons are not greyed out:

What is missing?
Also, luainputenc fails with more than one encoding in a document (see
http://www.lyx.org/trac/ticket/9740), so we should disable
LuaTeX with TeX-fonts and inputenc="auto".
