dilemma - liking a different baby name

Lisa

hello guys and gals, my husband and I are TTC right now and have had a boy name and a girl name decided on for a bit. If we have a boy we decided on Wesley Theodore and we've discussed having a daughter named Marley. but there is another girl's name that has really been growing on me and I'm trying to think of the best way to bring it up. I'm worried he might not be open to it and I'm starting to get attached to it. I really like the name Isabeau, but not sure what he'll think. Have any of you run into a situation where you already had some names picked out but one of you started to like a different one? Did you stick to your original or was the other person open to a different name? we are not currently pregnant so there is time.
