A dedicated separator for the cleanside is probably the best way to go but I haven't seen any kits.
While I haven't seen any advertised for the EcoBoost (other than the Elite CSS for the F150 (which the oil cap adapter may physically fit the transverse), the CSS "kits" that are out there appear to be simply the separator, a piece of hose, and a couple of clamps.

You could easily make your own kit with a few extra parts. Is Michigan an emissions inspection state, or are they OBDII only?
Based on your first post, I presume you want to be able to keep your engine cover in place.
Obviously, the primary objective is to keep oil in the engine and eliminate oil from migrating to the intake. The best way to do this is to remove the connection to the intake piping altogether.
The cheapest solution would be a breather filter on the valve cover. I haven't seen a picture, but this sounds like the BPD solution you mentioned. I imagine you may need to change or clean the filter once in a while as it would probably eventually get soaked in oil. Since your engine cover won't clear the breather, you could get a 90 degree elbow and a section of hose and remote locate a press-on filter to vent to atmosphere. This should fit under the cover, and if you route your hose with some thought, you can place your filter somewhere that would allow any oil in the hose to drain back into the valve cover, rather than pool up in a low spot. Even if the oil pools in your line, since this is generally under vacuum, it should suck oil back into the engine anyways. You could go one step further here and add a check valve that allows flow to the valve cover, but not out.
The CSS that replaces the oil cap is another, albeit more expensive, option. You could vent that to atmosphere with our without a check valve, or if you want closed loop, you could drill your airbox lid and install a hose barb, per Rx instructions.
Seems like everyone kind of puts their own spin on things, which I suspect is why you don't see a whole lot of vehicle specific kits available.
