I was wondering how directly chlorine usage is responsible for the ph rise in pool water. I am wondering if there is a way to quantify it, if it is. My thinking is... Would it be possible to add HCl (very dilute HCl I imagine) to my chlorine holding tank on my stenner chlorine feed system.

Insignificant. pH rise is usually due to aeration from SWGs, fountains, bubblers, etc.
Not if you enjoy living. Acid plus chlorine make chlorine gas, diluted or not. Chlorine does raise the pH when added, but then it comes back down as the chlorine is consumed. If you are having problems with your pH constantly rising your TA is more likely the cause.
So please don't add acid to your chlorine tank.

I do notice that my ph tends to rise gradually .. I am currently adding (via stenner) 38 fl oz/day of 12.5% hypo and its been working well. About one a week, I need to add 6-8 fl oz of 37% HCl. I usually add when ph is 7.8 and shoot to bring it down to 7.4 My HCl usage has been very consistent.
It is pretty normal for the pH to tend to rise ... unless you are using acid solid chlorine products.
