The idea behind using a name that starts with a D is to keep our existing logo so we continue to have some recognition. Creating a new logo defeats the purpose of sticking with a name that starts with D.
Initially, I was of the opinion that we should try to keep the Darkcoin D. But it will only matter to us if we keep it. If we are expanding to reach new eyes and ears, it will all be new to them. A big enough press release, along with redirected links, etc. will catch the attention of those who are already following us. So we should feel free to change everything. Bring on the new names AND artwork, and don't be afraid to try out names that don't begin with D.
