This reminds me of a blog post that I can no longer remember that discusses how Chinese is a lot of arranging several related kanji into a single character to express a new idea (please link it if you can find it).
I would love to see unicode characters to allow for arbitrary combinations beyond those defined using just ZWJ to allow more flexibility (e.g. blizzard could be created by adding like "slowflake x 5" which creates a single character with five snowflakes, without having to create an entirely new character representing blizzard from snowflake + ZWJ + snowflake).
As an aside, my favorite ZWJ magic is black flag + ZWJ + skull and crossbones = pirate flag.
