I'd just create a wrapper object that can point to either a db entity, or
an enum instance.

eg:

public class Wrapper {
   private MyEnum myEnum;
   private DbEntity dbEntity;

   public String getKey() {
      return myEnum != null ? myEnum.name() :
String.valueOf(dbEntity.getId());
   }

   public String getLabel() {
      return myEnum != null ? myEnum.name() : dbEntity.getLabel();
   }

   // getters and setters
}

Then you can create a list of Wrapper objects by combining MyEnum.values()
and a DbEntitiy collection from the database. Thi Wrapper list is then the
source of your select options.

Note: You'll need a suitable ValueEncoder to encode/decode.
