Perhaps. I figured the reason for making the "tea" is to sanitize the spices. Hope you don't wind up culturing some untasty microbes!
Also, the hot water probably helps release more spice flavor. No?
I think the tea also helps since most of those spices are almost insoluble in water considering their fat content. With that said, you can persuade them to distributed throughout the water by stirring the heck out of the spice tea. I know as stated somewhere on here that using vodka instead of water is possibly a better route.
