What you want is "structural" wood flooring that does not need a sub-
floor and goes straight over the joists.

It will probably be noisier downstairs though with people walking
about upstairs.

Chipboard and carpet is of course the sensible option :-)

IIRC Kahrs 15mm engineered said it was structural, with joists at up to 2'
spans.

I've also seen oak in 18mm somewhere.
