Just repack them and then rename them however you like, such as your_mod_name_meshes.db. You can put them in a directory, your_mod_name and put it into database\addons\
Xray will autoload all *.db within any directories listed in fs_game.ltx. It uses a virtual file system, it mounts the db's relative paths to gamedata. So last found file, takes priority.
This means say, you have system.ltx in database\addons\abc_config.db and there is a system.ltx in database\addons\xyz_config.db. The system.ltx from xyz will only be seen.
