If you intend on using the Micro optic, having deployed front and rear irons and a TLR-1 at 12:00 is going to work against the whole point of having a reflex optic. That's going to be a busy, cluttered sight picture.
I think that there are several configurations that work better than others. If using a Micro, I'd opt for a standard (center) co-witness with either a fixed or deployed folding front and a rear folded down. I'd mount a Scout light offset at 10:30 or 1:30.
Now if you were going with something that has a giant field-of-view like a Trijicon SRS I'd recommend fixed BUIS.
