No, the format is not extensible.
The TNG format offers better compression than XTC, and in principle can be
extended for this kind of purpose, but you'd have to write some C/C++ to
get that organized. An easier approach is to keep your B factors in some
file that you keep in sync with the XTC yourself, somehow. Then build a pdb
frame when you need it.
