If they are meant to be mystic adepts, so that Channeling metamagic could actually apply, then a whole host of detractions come into play that would in all likelihood melt the possessed mystic before he even steps into the ring.

And how does that work out?
In order to summon a spirit of Force 20, one needs at least a Magic of 10. For a Mystic Adept, this would be 10 in the magician part of his split, aside from the adept part. Drain from this summoning would be Physical, unless we are looking at a Magic of 20. Let's not go there.
So the Mystic Adept with Magic 10 attempts to Summon a Force 20 spirit. Let's give the Mystic every benefit, so a Summoning Skill of 6 with a specialization in the particular type of spirit, so 2 more dice, plus a Force 6 Focus appropriate to the Summoning. Hell, let's give him an Aptitude in Summoning. That gives him 10 + 7 + 2 +6 = 25 dice, versus the spirit's 20 dice. This assumes that a Force 20 spirit wouldn't consider a human at half its Magic and less than half its intelligence and strength of personality as an inconvenient insect to be stepped on with the use of Edge. An Edge of 20. But the Mystic happens to have Spirit Affinity for this kind of spirit, so it doesn't squash him immediately. Chances (slightly better than 50-50) are the Mystic will get about 1 more success than the spirit, so it arrives.
Then comes the Drain. With the use of its Edge the spirit would get about 22 hits, which would give a Drain Value of 44P. Squash. Without Edge, the spirit gets about 7 hits, which translates to a Drain Value of 14P. The Mystic, who also has maxed Mental stats gets 12 dice to resist Drain. This gives him about 4 hits, so the Drain is reduced to 10P.
oh.
Wait a minute, the Mystic
really wanted to use Edge on the Drain Resistance Test. Here he finally runs out of the Max-Minning, and is better off re-rolling misses. So 8 dice give him about 3 more successes. He is at 7P Drain damage. Still up and
running staggering. The possession itself will be trivial with that Force of spirit and a weakened resistance on the part of the Mystic.
So after every benefit in favour of the Mystic Adept:
Magic 10... (OK, this is a minimum requirement, but come on, it cost him roughly 230-250 karma to get there after chargen)
Summoning maxed...
Aptitude in Summoning...
specialization...
massive focus...
Spirit Affinity... Edge use only on the part of the Mystic... (sort of related)
no bad luck on any of the rolls...
... the Mystic Adept is 3/4 dead.
