Steampunk - Magical Control of Steam-Bots

[Nedorus]

I'm currently working on some ideas on how to implement this.

1. Similar to Sorcerous Empowerment + Steamjack-limited Buff-Spells (like the above ability)
2. Possession with Telecontrol and/or Compartmentalized Mind and using Imbuements on the Steamjack being possessed but using the Warcasters IQ and imbuement skills
3. Adaptation of the Steal Skill Sorcery Spell taken from Aleksei Isachenko's Blog 'Generic Universal Eggplant' and letting the Steamjack 'steal' an imbuement skill from its warcaster and use it with his own IQ.

Option 1
I really don't like 1) very much, as I want to use a form of Symbol Magic for the dedicated Mages as the background lends itself to magic being based on runes etc.

Option 2
What I have right now for Possession turns out to be REALLY expensive. The way I want it to play out would require one level of Compartmentalized Mind per Steamjack in the Warcasters Battle Group.
I'm using some modifiers like Magical -10%; Mindlink Required -40%; No memory access -10%; Specialized (Steamjack Cortices Only) -50% (the largest limitation per RAW is -40% here but I feel this is "more"); Limitation: Can only use Imbuements in the possessed body -50% (these are really already quite liberally applied)
But there are some heavy Enhancements that I would need: Ranged +40% + Reduced Range 1/10th -30%; Reduced Time 1 (make the possession a free action) +20%; Telecontrol or Telecontrol 2 +50% or +100%
this brings Possession to about 40 points
The cost for the Ally, Mindlink, Puppet and Compartmentalized Mind sums up to an additional ~65 points... Each additional Steamjack Ally would be ~55 points as possession is only necessary once.

Option 3
I haven't run the numbers yet. But the idea would be to grant the Steamjack the power to borrow / steal a skill (Imbuement skill) from the Warcaster and pay for it with the casters QP using a reverse version 'Drains Familiar' ability (DF5:20) called 'Drains Warcaster' which is really a very basic QP-Energy Reserve costing maybe 1 point each.
Aleksei built the Sorcery version of 'Steal Skill' on Telepathic Learning which is a modular ability from PSI16 throwing in a Power Theft +200% enhancement taken from the Neutralize trait. I really like that idea!

OK, now you know what avenues I'm checking out to find a nice solution.

Questions
While crunching the numbers on Possession I started wondering how a Compartmentalized Mind and Possession would work:

• WITHOUT Telecontrol
• with Telecontrol
• with Telecontrol 2

Does this suggest that I need neither version of telecontrol if I have CM as long as one compartment 'stays behind'?
