I did that as well Snn5. I created an actual ICE group with the same group members. So far everything continues to work correctly, and my new ICE group still appears at the top of my list.
This experience has led me to start seriously thinking about upgrading my device from my LG LUCID2 (my beginner smartphone) to something with more storage and a bit more oomph - currently leaning towards the Motorola Droid MAXX for the battery life. Taking in a lot of the feedback from the forums here.
