To be honest, Just like this isn't a do-all rifle.. no matter what no rifle will be do-all wihtout swapping in and out seriously hefty parts.. there is no do-all optic either. I suppose in theory you could rig up a couple of uppers (possibly in different calibers) with a couple different optic situations... or just decide that these are the three objectives of the rifle, in which case you may be able to settle on one optic, or two with QD mounts.
As for splitting the red-dot/magnifier... I did, I have a strikefire, and VMX3 on a swing out mount. I haven't had any issues using it off hand, or off bench. I haven't even felt the need to swing the magnifier out of the way, though it's fairly simple and easy to do so.
