Being a fan of Nanoha and Rayearth, I gave some thought about how it would work, when the idea came to me:
Pair ups:
Nanoha -> Rayearth   (I think this one is obvious)
Fate -> Windham    (Fate here is the caring one, while ...)
Hayate -> Selece (Ceres?)   ( ... Hayate is the tactician)
The Cephiro-type magic could synergise neatly with the mid/belka-type--it all works on willpower anyways.  Although I'd be kinda scared of Nanoha's power at the endgame.  (These three piloting/riding a living mecha that augments her own powers, which in turn are augmented by the nature of the world, and her device.  Yup the end battle would be a curb stomp.)
As for justifying the need of the rune gods, the Zagato can affect the world as a whole with his powers (and the pillar being out of commission), and even our heroines can quite cope with that in the beginning, ending up with a stalemate, until they can break it bu unlocking the power of the Rune Gods to level the playing field.
It'd be curb stomp fun, but there's the possibility of legitimate story there, I think.
