Hmmm.... Decisions...

I have gotten into the habit of nonstop spamming mana and health pots anyways. I always have plenty enough mana and struggle with health. Mana shield only lasts so long and health is open for attacks a lot more then mana. So nothing will change when I switch over, other then the fact that I am now generating slightly more h/s and less m/s. Pure int mages usually spam both pots nonstop anyways.. or else they are toast in the sewers.

Edit: have you also put the 6-8 extra int into consideration? I am a damage junkie, that 6-8 int doesn't add a lot by itself, but all spells combined, it adds a hefty bit of damage.

I rarely if ever use a mana pot, and use few health pots in full Mega Mage.
Edit: and as I said above, H/s won't save you from using health pots. There's no time as a low armor/ low health mage to wait around for health regen to slowly replace lost health. Do as you wish, but if you try out a low mana regen, high health regen setup, it won't be long before you're shopping for Mega Mage. That's what killed Int mages at the 40 cap. Elite Int gear at the time had high H/s and even armor and dodge but was terrible in practice and almost all mages turned pally (this was the dawning of the pally era) because Str gear had mana regen.
