Couple of things...first up, you really don't want a mono output, especially with that Beads in there. The output module also has connections for the Intellijel (I'm presuming that's what's specced here) case's 1/4" jacks, so those are a tad unnecessary, meaning you shouldn't have a problem adding in the normal stereo out. For that matter, I'd consider tossing the mult and scope tiles as well; scopes are nice IF you have room for them, but a 7U x 84 case like this doesn't have that room. And as for the mult, you can jam more functionality in by chucking it and going with inline mult widgets, since there's no need here for a buffered mult, apparently.

Better choices? Well, here's a layout for the tiles that makes loads more sense:
ModularGrid Rack
Now, here you've got another FX processor, which will be useful for "stereoizing" mono signals. And that dual stereo mixer gives you hot outputs for more modular processing while, at the same time, it also provides your stereo output at line level via a pair of the cab's 1/4" jacks, AND you can mix your FX tile's stereo out and the Beads' stereo out right there for your final mix balancing. Definitely more useful!
