Not to my knowledge. Among other things, that's what trjconv is designed for.

4.5.5 is the newest version, and the inability to read .g96 is still present in
the latest development code. I suspect no one has had a need for .g96 format in
quite some time, so it has been ignored. The issue will certainly remain
