Hi. There is no easy/supported way to do that, I'm afraid.

The mod relies on static titles, which the game only adds to new savegames, not if the mod is loaded mid-playtrhough. It might be possible to manually edit a save file and insert the necessary titles (meaning d_CTFA_vanity_0 through d_CTFA_vanity_63 for the current version) and variables there, or copy them from a new savegame created with the mod active, but I haven't experimented with it myself, so can offer no guidance there, let alone promise such a modification would even work.
