Center channel Impedance.

[E-Stat]

Most people get used to it and the brain compensates by creating a virtual audio image across the screen. In my case, that has never happened.

Such is the same for me, too.

My solution was to use a Yamaha receiver that has an ambience channel. This is comprised of 2 extra speakers that enhance the sound by creating extra ambiance, but also has the ability to add center channel information to those 2 speakers.

I'm not sure that is the best approach either.

I have Magnepan wall speakers and I was reading about using their center channel speakers with two additional wall speakers flanking both sides of the screen to get the same effect that I mentioned above.

Interesting approach, but might still involve the same challenge with loss of separation.

Is it okay to run speakers at 15 ohms and is there anything else that I need to be concerned about?

Wiring different speakers in series is not ideal. Multiples of the same is fine. An amplifier won't have trouble driving the load, but the time response to the speakers will be affected. I might try using two of the identical speakers as the center with their height aligned with the mains. Just like they do at commercial cinemas.
