Yeah I am not sure about how well you could make a vortex bowl, but hey who knows! The main thing with it being a Lebanese as stated before is that you are limited to the one type of bowl. All I can say on the hookahs themselves is that I have the exact KM that you are looking at and it smokes like a champ and is beautiful! But all we can do is give you suggestions and you gotta do what looks good to you!
Here's hoping I helped some
