 why not? hash the emoji and derive the private key by the hash, then generate the recovery words from the private key 
 If I get this right, this: 
- only works in one direction
- would be a bit less random (or actually quite some bits lol 🙈 )

Both of which I'm more or less fine with.   
 yep, there will be no way to get the emoji back from the hash, but you can always recover the account if you have the emoji and as for randomness, correct, if someone knows that you use an emoji key they "only" have to try all the possible emoji instead of all the possible words in the wordlist. it's a compromise for sure, but it's a fine one for the average person (and if you need more security, just don't use this system!)
