Hello and welcome! I get what you mean about wanting to make something different and fun, and I'm glad to hear that you are open minded and researching a fetish that you hadn't tried yet. Also, great to hear that you get to run this business together with your husband! Having a fun time doing this stuff and being married to a guy who enjoys it with you, I am quite happy for you!
I do have a few ideas as well. Not whole ideas for a script, persay, just tidbits and scenario types to maybe get your inspiration going.
-One thing I haven't seen or heard much of in the realm of realistic (live action or 3d-animated) depictions of vore is willing or pleasure-intoxicated prey. One of the biggest aspects of the fantasy that I like is when the predator wouldn't... normally eat the prey. If they are friends, or lovers, etc. But they just get so turned on and carried away in the pleasure of the act, possibly both of them, that they let it happen and enjoy it. Or the prey wouldn't normally let themselves be eaten by anyone, but the predator seduces them to the point where they want it. This can be done well with lethal or implied non-lethal vore, although I suspect a lot more people would enjoy it with the implication that the prey is not seen again. I personally love the idea of vore as an extreme act of love which lovers or a couple only do on rare occasions (or only once!)
-Another idea that might interest you is a predator who isn't necessarily turned on by vore themselves, seducing and devouring prey under the act of a "threesome" or some such as a gift and special show for the other participant, who loves it. I don't know if your husband sometimes features in these films or not, but a husband or wife devouring someone for their spouse's pleasure or for mutual enjoyment is an idea I love. If you couldn't tell, I love romance and fantasy put together!
-On the subject of willing and non-lethal vore, one thing I personally love is when a predator swallows (or unbirth or AV) a friend or lover, and keeps them inside for a while with no visible bulge. It defies physics, and different stories describe it differently, but I personally very much love the idea of having a whole other person hidden away inside me like a naughty little secret. Or being hidden in that way. It could be used for anything as extreme as smuggling a secret agent through a security checkpoint, or something as mild as smuggling a best friend into the movies. Or just for fun.
There's also the subject of other types of vore besides oral (Unbirth/Vaginal vore, Anal Vore, Breast vore, Cock vore, etc). I haven't watched your productions, and I don't know what kind of special effects, if any, you can use. If you mostly use camera perspective and good acting (possibly the horror-film style shadows-on-the-wall trick) then oral vore, and perhaps a few of the others are feasible, but I'm not sure how CV or BV could be conveyed very well visually without some added effects. If you are interested in exploring some of the other ways to get someone inside someone else, that would make me happy, but it's already amazing to hear that our fetish is appealing to creative-minded artists who don't necessarily share it.
Also if you are looking for ideas that might appeal to you or some of your actors and actresses, you might consider checking out some of the art galleries here! Especially for ideas on what some people here would like to see in live-action, you might want to check out the photo-manipulation and morph subforum here:
viewforum.php?f=88 where some people edit photos and frequently add story captions as well.
There's a bit of nearly everything there, so if you do a bit of poking and scanning through, you'll probably find something you like for story or script inspiration.
