Yes I guess that would be fine, but maybe with the X-pan, I would spare some vcas? I have to start with the upper row, and I only have the new veil in that row (if I follow your suggestion, which I probably will). Additionally I do not have a proper output module on the upper row to begin with, and I planned on using the X-pan as a stereo output module to start with, and use the vcas available to control the volume... I'd rather avoid buying an output module twice.
I'll think about it for a bit... and post a revised plan for the upper row only in the thread
