Well, the idea I had for Inquisitor is the High AP Inquisitor - taking the Warlord Talent and loading up on skills which grant extra AP. Starting Combat Abilities are Warfare and Pyrokinetic, starting Skills are Battering Ram, Haste, and Flaming Daggers. Everything else remains the same, including the Warlord Talent.
At level 2, take a point into Scoundrel and pick up Adrenaline. This helps to make the Inquisitor into more of the Speed Mage which it was in D:OS 1.
This is similar to what I wanted to suggest for the battlemage so that Inquisitor can get Aerothurge and Warfare, the only thing that prevented me to follow up on this ideea is the fact that I don't see for the life of me why a staff wielder would want (more than) 1 point into Warfare seing that the bonus is so useless to them....So I tried a poly and aero combo on a staff wielder and found something very interesting, the skill bull rush actualy gets bonus from Inteligence and the elemental damage from the weapon he is using.
For a preset on Poly and Aero I would go, Ligthing Bolt,Lighting Hand and Bullrush as I feel Chameleon Cloak in place of any of the mentioned Aero skills would make the class to "safe" to play (charge stun/burst down magical armor then disapear at your earliest convenience).
