ReaxFF in GCMC

Dear Lammps-users,

I want to study hydration of salts, therefore I want to use GCMC with ReaxFF.

So my question is if this is possible with LAMMPS, and if someone has done this before or has a comparable example of ReaxFF in fix gcmc?

(I have read some previous contradictory mails about this, so I guess some are outdated)

Thanks a lot!

Kind regards,
