The thing I like most about your solution is that YOU were wondering if it was too close and YOU decided for your peace of mind to change it to something you were more comfortable with. I have often found that running a potential problem by people, either online or in person, helps me most by telling me that I'M not comfortable. It's great to get the feedback, but the biggest help sometimes is the sounding-board effect of hearing myself ask the question. That helps me decide to go to the trouble of changing things.
