I could be wrong, but I've never heard of that happening. I know the
chloroplast can communicate with the nucleus using abscisic acid,
sucrose, H2O2, O3, xanthoxin, tetrapyrrole, etc. But I've never seen
a report of a protein being exported from the chloroplast to the
cytoplasm or nucleus.

Search for "chloroplast retrograde signaling".

Why not encode your gene in the nucleus and have it produced by
ribosomes in the cytoplasm?
