You're looking for functional encryption (https://en.wikipedia.org/wiki/Functional_encryption). It lets you compute exactly an encryption of a pre-specified function of the input message and nothing else.

I think functional encryption is even less well developed than FHE. Most problems can't be expressed in functional encryption, and the security model is really iffy.
