Super Puzzle World 3 has a lot of easter eggs if you look way deeper in Lunar Magic. I can't recall any other hack that has them, though.
Easter eggs are fine, but like others said it depends on what reference you're going for. There might be some people who can't get it, but the ones that do so at least had their fun at trying to guess so; in other words, referencing another hack through those would be more feasible if that hack is really popular or something.
Thanks! I explored this hack a bit and I saw stuff like annoying messages like "Welcome to Lunar Magic... Cheater!" just when I opened it, or "Choose a starter home. Choose your friends. Choose leisurewear and matching luggage." in a... Megaman stage? There was as well a lot of 8-bit games references like Super Mario Bros 2, Metroid, The Legend of Zelda, etc... Which also contain strange messages but too vulgar to be cited. Anyway, I had never saw this before so that's something interesting even if there wasn't references to others hacks.
Oh and you got right, reference to hack could be good if the hack is popular.
P.S. :I tried to play this hack but I'm just a basic human...
EDIT: Sorry I just realized that my english is really bad, and sorry, I'm too lazy to take screenshots..
I've tried one time, I was with some friends, and one of them bought a cigarette which have a chocolate taste. He proposed me to try, and it had a strange taste mixing chocolate and smoke... That's why I will never smoke again.
I like the story, I think it will be as awesome as your current project. So this is a non-Mario hack which will look like an Atari 2600 game, with the graphics and sound effects? And what about the music? Will you use 8-bit styled ones?

Each level is loaded as a single screen and when the player reaches the end of the screen a new screen loads in its entirety like in the SNES game Another World.
I believe that there are some hex edits to totally disable the screen transitions, so it might be more like Another World.
Anyways, finish Super Mario Logic, then attack this! Good luck!
