The only ones I'm aware of are like this one.

It has a 10ml reservoir, you put it together and it rides on top of a traditional hookah bowl. That's what would determine how many hoses etc. Chris from Indoorsmokers reviewed it.
I'd think it would kill flavor as well, not only is it travelling through a long hose it's running through a bowl of water exactly like a traditional hookah. The difference is smoking tobacco through a hookah, the water helps act in place of a filter on a cigarette and filters out some of the tar and impurities. Not sure what impurities it's filtering out of vapor besides flavor maybe. Everyone would be better off with their own mod and rda's if everyone wants to vape the same flavor. Using a bowl of water with vaping seems like using a gas mask in a clean office that's already providing clean air (aka sans smoke, chemicals etc).
Just like with a regular hookah, in order to get vape out of it everyone else with a hose will have to cover their hose end with their thumb or something so you get suction enough to activate the vape head. Might be novel, not knocking it and if everyone is familiar with it should work ok. Otherwise a bit of a pia over having a mod in hand.
There's a whole variety of bases and stems out there I think that amanoo head is compatible with. If going for a real bachelor pad theme, there's the hobohookah portable stem. You provide the bottle (wine or similar) and it slides over the top of it.
