A large challenge with this is that you only get 1536 characters in the MOTD when it's sent from the server like this. This limits how much HTML/CSS that can be used to make it look different. Also, it's not possible to read your mind to determine what "aesthetically more pleasant" means in your mind since this is a very subjective thing.
Just a little advice, if you're using the default plugin with no modifications, please tell us that and what version of AMX Mod X you're using. It's much easier to get the code into my editor with the proper whitespace.
