This question will need some additional information, so I hope I don't enter the TLDR state; but I think explaining the scope of the question will help with answering it.
I wanted to create a run for our group with a System-Shock atmosphere (but without a KI) while allowing both the Awakened characters, the fighter and the technomancer, to really make use of their abilities outside of combat. I'm not very experienced, so the complexity involved here might be a bad idea, but at the moment it's just a premise: An out-of-control (from the corporation's point of view) base completely under control by a mage who also controls the computers, cameras, robots etc. of the base.
I know that the rules don't allow mages with technomancer powers for obvious reasons, but here it's about the bad guy and I was thinking about the following:
In the base heart, the awaken was placed in a really advanced MRT machine and connected to an EEG. This avoids anything needed to be plugged into the poor fellow which would reduce his magic powers. The only stuff entering his body are for feeding and keeping him paralyzed. The MRT/EEG monitors his brain, translating his thoughts into commands for the computers of the base while, via magnetic manipulation, feeding back information to him. (There are some experiments even today showing that you can manipulate a brain via magnetic fields, and hey, it's the future!) So the poor victim of the corporations is able to control the computers and gather information from them while not losing his magic powers.
Sadly, the way the corporation used to control him failed and now the whole base (a claustrophobic bunker underneath the surface) has gone berserk. Enter the runners. (The corporation could solve this somehow, but they built the thing completely autarc, and the local commander doesn't want them to know he ruined it (it was costly!) so he prefers to hire runners over informing the board. Hence, runners.)
Is this — in a Shadowrun sense — reasonable?
Is there a way to amplify the poor fellow's magic powers as well so that he might use magic throughout the whole base?
