I Guess You Could Call Me A "Revolver Guy" too!
There are many custom makers who can competently give you what you ask for. A few of them participate in this forum. Some are old timers, some are new to the craft but have plenty of talent and may even offer fresh design concepts. I'm sure a few of them will pipe up in short order. Call me a dinosaur, but I probably offer more revolver IWB designs than anyone on the planet, or, at least that's what I've been told. Here's just a couple of examples with offset clip tabs over the triggerguard to reduce cylinder bulge.
DEEP DROP BANDIT
I can drop this rig as deeply into the waistline as you want to go. Shown with the standard 3/4 combat grip.
SUMMER HEAT
Same deal here, just tell me how low you wanna go. Shown with full combat grip.
These designs have slightly different features, shrouded hammer, open muzzle, stitched muzzle, etc. They were inspired by my pal, the late Chic Gaylord, and his early design of the "crotch holster" used by many undercover federal narcotics agents during the 1950's, with some significant changes, but that's another story entirely. Our clips are custom made from gun spring quality steel and they will not draw off, whether you wear it with a belt or not. Clipped to the trouser waistband and covered with a belt, 95 % of the clip is concealed and entirely secure.
As an aside, I agree with your observation about many manufacturers limiting their potential by only display advertising their rigs with autos. But the mass manufacturers have a different agenda which is targeted at volume sales. The industry gurus claim that revolvers represent less than 10% of annual new gun sales, so auto loaders are their target market. Advertising is very expensive in the gun rags and the bean counters at the major holster companies calculate their returns on every ad they place.
I decided long ago to take a different direction as a custom maker at a time when everyone else in this industry said the wheelgun was dead. All the law enforcement agencies were transitioning to auto loaders, but I stayed my course. The "shall issue" CCW phenomena was only a glimmer of hope back then in many states. The internet didn't even exist. All of that has changed in the last 10 or 15 years. I watched as the defensive revolver's popularity was resurrected like a Phoenix rising from the ashes. Today, I have nearly as many loyal CCW clients as I do military and law enforcement officers. 1911's and hi cap polymer guns may rock the world for many shooters, and of course I craft rigs for them too, but my market niche has remained true to my personal preference. The revolver is not dead by a long shot, pardon my pun! Cheers!
