Please help! I need to pick a wedding ring (pics of e-ring)

We're getting married in February, but our jewelry store is doing a 20% off sale only through the end of the year. I'd ordered a plain flat band. I went to pick it up and didn't love it with my ring. It looks... okay. I really don't care for the matching set (the engagement ring with the intended band that matches it exactly). I need ideas of what to do! My FI couldn't come to town before Christmas so he's no help. I am so worked up about this. I know that if I don't get something pricier while the sale is on then I definitely won't get it later. The price isn't the issue, and FI agrees.

I tried on my e-ring with the matching band and I didn't care for it. My center stone seemed to get lost in all that bling. For reference, my center is a 1.2 carat and my ring size is 4.5.

I tried a really wide plain band and I hated it. I knew I wanted a very narrow band, which the one I ordered is 2mm, but it's still too wide compared to how narrow the diamonds in my channel set are.

I was even thinking now that I could do 3 rings... engagement, wedding band, and another one. A friend has these in fashion rings with her diamond mounted on one. For sentimental reasons my FI would be heartbroken to change my engagement band in any way.

Here are pics of my ring:

Here is the band I ordered. It's flat and plain and 2mm wide:

Here is a picture similar to what the set would look like (I don't like how matchy matchy it is)

Any ideas of what to do?
