I don't think it will be possible.
Each application name will get the name of the ear file that gets deployed by the python scripts available in <WAS>/profileTemplates/odm/decisionserver
and I am afraid changing the ear file name will break the scripts (the script won't find the file if you edit its name)...
And once it has been deployed, the application name cannot be modified anymore in WAS Server...
