Yikes! FICM is a good chunk of change from Ford. Battery/charging issues are hard on the FICM I would check it cold. It has a larger load on it then and battery voltage is at its lowest with the GP's on. You may also want to double check the connectors, there a booger to get to but if not clicked in all the way they can be an issue.
My truck acts the same as you describe and FICM volts are good. Rev X cleared it up for a while so I think it's an injector issue.
You've likely read several posts about em, but a Scangauge II is a great addition to a 6.0, you could check all this FICM stuff from the drivers seat in about 30 seconds.

I don't see any smoke from mine. A leaking injector would be different. I just got 1 or 2 missin (sticking) when there cold. Everything's goo by the time oil temp gets to 85f or so. That scanner should be good for codes (CAN compliant) Snap-on sells pretty good stuff. It would need to be able to do a cylinder balance test to really check injectors but it will show a bad one if it or it's "channel" in the FICM fails. Ford and AutoEnginuity are the only two I know that does that.

Just from what I found with my FICM. It took 10-12 seconds for my FICM to go from 40v to 48v at cold starting point. After my truck was warmed up, my FICM always read 47.5v-48.0v.
Not sure what you check your ficm with. Just thought I would throw this info out there.
