I'm not sure about an EOTech mount on the "hump" but it may work. There's room behind the hump for an ACOG. And, IMO, it puts the Aimpoint in the perfect spot on a standard M4 carbine configuration. It's also great in the above setup with a LMT fixed rear. If I ever build a Mk18 Mod 0 type rifle, I will use a RAS II instead of the RAS for this very reason.
Before I sold that upper, I had switched to a SureFire Scout in an offset mount (Gear Sector) and it really freed up some room on the right side of the handguard (as well as weight).
