Need Help Princess cut center stone w/ trillions. Wdding band help.

Hello,
I am having a really hard time finding a wedding band to match my engagement ring.  I have a Princess cut center stone and trillion side stones.  I just have no idea what to get.

Obviously nothing is going to sit flush w/ it.
I am debating between the following:
1. Getting a band and just not worrying about that they don't sit remotely flush to each other.
2. Getting one molded to fit around my engagement ring. BUT if I do that my question is say my e-ring turns to the side like they do sometimes when your hands are cold, etc, will the band move with it or will it have this weird outline that never seems to be fitting nicely w/ my e-ring.

Then my second dilemma is
Do I get just a plain band or one w/ some small princess stones in it? Should this be dependent on whether I get on the that sits flush or is molded?

I have gone and looked a few times and each time I feel more and more confused.
Opinions greatly appreciated.
