I suppose this might work, but in our torquing application we're pushing stainless steel knife edges into a soft iron gasket, so we get a decent amount of bolt rotation for the first few cycles (while we're squishing the iron, essentially). Once we get to around 800 ft-lbs, the two parts go line-to-line and we're putting the compressive loads directly into the stainless parts at that point.
What we do now works, but we're having a sealing problem that might be a function of the torque and I'm not really able to defend our torquing method and am looking at better options.
Our access is relatively limited also. Here's a picture of the bolt pattern:
