I will forward your question to Dr. Elliott Bondi, a grandson of Rav 
Breuer, who will probably be able to shed light on it. YL

As I mentioned earlier, I sent a copy of your message to Dr. Elliott 
Bondi, who is a grandson of Rav Yosef Breuer, and hence a great, 
great grandson of RSRH. He is an expert is the writing of RSRH and 
is one of the editors of the Collected Writings of RSRH. He replied

No.
Rav Hirsch cites sources if he drew on them. He did not draw on the
Kli Yakar.
