Michell actually had a version for two arms at one time (pictures), though I never saw it offered for sale. I am guessing you plan on bypassing the suspension? The TT has a 1Kg. wt. limit for an arm+base so I am guessing that limit has to be split pretty evenly for a 2 arm set up. I read where the two arm units had to have the densodamp removed from under the second ear to mathch the weight of the 2nd arm. I don't really see it working too well if the suspension isn't bypassed. I'd send an email to Artech and ask for details. I've always gotten good advice from them.
I was contemplating the same move and I be interested to see what you do. Keep us posted or drop me an email.
