I believe you completely misunderstand me.

Your session runs at a sample rate set by JACK.  All the files that have
audio in them  have to match that value.  If the audio you want to use has
a higher sample rate, it will have to be re-sampled at the lower rate for
Ardour to use it in that session.

If you want to have JACK and Ardour run at the higher sample rate, assuming
your interface supports it, you'd have to create a new session and import the
tracks.  The files with the audio that match that new, higher rate will be
imported with minimal processing, while the other tracks will be up-sampled.

There is no way for Ardour to use files of a different sample rate without
them being resampled to the rate of the session, as determined by JACK's
