I know it's possible for Oculists and Telepaths to work together to make controlling  demonic servants easier but would any of the following combo's work as well? 

A Telepath and a Mystic working to read someone's mind or control someone from afar. 
Alteration Wizards and Necromancers to both make the corpses less recognizable or better "equipped" for their new task.
A Mystic helping a Planar Mage to find the right formula's
A Mystic and An Alchemist to find the best ingredients. and finally Alchemists boosting the power of Destruction Mages with poisons and flamable oils.

Of course there are many more combinations possible, these were just the ones I could think of.

Yes to everything :)

You could also do things like:
A Mystic and Destruction Wizard working together to attack from miles away, through a Seeing Stone
An Alteration Wizard allowing a Planar Sorcerer's portal to stay open for longer
An Alchemist increasing the raw power of any other mage through potions
A Telepath controlling someone's mind while a Mystic controls his body (voodoo), so that they have complete control over some poor individual.

And so on. I intentionally made some of the "classes" so that they may be able to help eachother, thus making our different characters able to work together in interesting ways.

My character is a Mystic (will be presented soon, I assure you) and the Prince is a Telepath/Alterist, so we should all have plenty of people to work with.
I mean, we have several Occultists, three Alterists, two Mystics, two Telepaths, two in Destruction, an Alchemist, and so on. I think every type of magic has been done at least once.
