Inspo from the shop I went to today. They also recommended just putting the marquise in a bezel, but I want to use the side stones if possible. 
The first ring I saw that I really liked, but I think my stones will be too big.

My ring
Very new to jewelry, but so happy to have found this forum!!
I have a very outdated ring from my mum that I want to have reset. I popped in to a shop today to have something else looked at and while there, got some thoughts on how I could change the ring, but I wasn’t in love with any of them.
My first thought was that I want a ring for my right hand where the marquise is on its side (east west, is that what it’s called?) with stones on the sides but with a thin band - the place I went today though didn’t sell me on their ability to do that. I definitely don’t want anything that reads engagement, but am open to any ideas you all may have! I also have some small small square diamonds that could be used as accent stones.
Attaching a picture of the ring as is and a couple of ideas. Have already contacted David Klass as well after scrolling through the posts, but still need a starting point, I feel like. TIA!
