As a matter of fact I made one, even posted some rules on it.
hypnohub.net/forum/show/24665Never got any comments on it though.
TBF, the only thing you'd really need to add into Shadowrun is a system of long term suggestions and overcoming it with will. Probably something along the lines of an Intuition or Logic skill 'mind control'. If you used long term test rules set to about a half minute or so, with something like 1-4 dice per 'success' on a given suggestion, it would be fairly interesting. That's the simple start, the sky is really the limit in that system, especially since certain bastards (particularly Deus in the Renraku arc) tamper with the human brain extensively, with fairly interesting results.
Otherwise, you already have BTLs, Trid Illusion spells effective enough to fool electronics and magic that bluntly controls thoughts or bodies (mob mind and control thoughts iirc).
