I can't answer your specific question - but I will say that you will have a tough time fitting all that onto the PS90 - There is 1 guy here that did it using a longer rail that he slid onto his PS90 rail. That's pretty much the only way you will fit that.
Critical Dimensions used to sell a slightly extended PS90 top rail that might barely have all of that fit.
Good luck :?
