After reading this message more carefully, I can confirm: different "tbn"
values in the files will cause timestamps to be wrong with the concat

This one can probably be adapted relatively easily, yes. I am reluctant in
adding new matching / conversion features (because I would like to find a
scheme that can be both simple and generic and avoid an accumulation of
specific options), but adding the required rescale operation would probably
do no harm.
