The logic is that stamina is a form of endurance and using spells in some fiction places physical burden as well as draws on magical reserves or external sources.
I've already got a bee in my bonnet MagSorcs are hybrid. Tri stat pots / food / amber / shackle / engine guardian. Just to sustain.
Personally I'm id prefer more clear divides of pools. Not less.
I see your point, and like I said in another thread, the same goes for stam builds. Cloak, streak, dark deal... you name it. While not as detrimental as rolling or breaking free, those are still essential parts to them, so I see where you're coming from.
But honestly, I am tired of the mag/stam dichotomy. No other TES game forced us in such a pigeonhole. Only reason is to artificially create more "classes". If I want to be a spell casting weapons expert, let me. The old issue of people putting all stat points into health could be solved differently than with the current method.
However, I don't see a point in multiple-cost skills.

As an alternative to adding new hybrid-style skills like described in the OP, I'd also like to see the following:
Hybrids being required to wear Pelinal's Aptitude and split their stats between the two penetration, critical, and (up to 3) recovery types is more than enough of a tax, so let's remove other avenues of splitting.
Remove the damage scaling based on resources entirely. Let the few skills that scale off Max Health and pets/summons continue to scale off of resources - no need to rework them. To compensate for the nerf this would cause on Sorc pet builds, add the following effect to the Expert Summoner passive: "Increases your Spell Damage by x% while you have 2 or more Daedric Summoning pets active." The x variable can be balanced appropriately.
Reintroduce diminishing returns, but only to the Health resource. Add a new effect to the Heavy Armor skill line passive, Juggernaut (currently just increases health per heavy armor piece), which removes the diminishing returns on Health.
Revamp the 3 and 4-set bonuses for Pelinal's Aptitude. Have the 3-set grant both Stamina and Magicka Recovery (at a reduced rate similar to that of dual-stat foods compared to single-stat foods). Have the 4-set similarly grant both Weapon and Spell Damage (also at that reduced rate, even though the 5-set bonus will only cause one to count).
I'd bet my account and everything in it that this selection of changes would make Hybrids viable while keeping them relatively balanced with pure builds, all without nerfing the pure builds.
