I'm afraid that theatre organs are a minority interest - both in the real world and within the Hauptwerk community. Much as I love them, we have to accept that their heyday was the 1930s - ninety years ago. One established Hauptwerk company - I think it was Inspired Acoustics - mentioned some while ago that a "significant" theatre organ was under development, so it will be interesting to see what happens there.
Another problem is that theatre organs are not so varied in specification and sound as straight/classical/concert organs. Of course there are differences between the sound and general approach of organs by Wurlitzer, Robert Morton and (in the UK) John Compton; but those differences are much less than between a large romantic cathedral organ and a baroque instrument like St. Laurens Alkmaar. Consequently we don't need so many sample sets to represent the world of theatre organ sound.
Nevertheless there are wonderful opportunities for an enterprising samplist - for instance the 5/27 Moller which was commissioned by Reginald Foort in the UK as a touring organ, became the second BBC Theatre Organ, spent a while in Holland and is now back in America (Pasadena?). Still functional in the UK is the magnificent dual-purpose Hill, Norman and Beard/Christie organ in the Dome concert hall in Brighton. That organ has a sound of it's own, with a particularly beautiful Harmonic Claribel and superb high power reeds. But given the time and expense involved in producing sample sets of these instruments, I'm not certain it's realistic to expect virtual versions . . .
