That's a really interesting question, I had hoped someone else would have chimed it by the time I signed back on.
My gut tells me no. The reason why I think that is because it seems all of the water adjustments we do seem to change the flavor of the beer and not really the aroma. "Hotness" to me seems like a flavor/aroma combo... you get a waft of it when you smell the beer because it burns your nose a little, and then when you taste it, it not only burns on the tongue, but it continues to creep up the back of your nose.
For me, water adjustments are all about the "feel" of the beer on your tongue.
And that's my completely unscientific opinion.
