Lemieux on the PP is ridiculous. Chytil, Buch, Kakko and Gautheir are all better options. Kreider is elite net front and he's elite at retrieving pucks on the PP. Lemeiux just can't fill that role.
My concern as I said earlier was losing Kreider causes Quinn to go galaxy brain with his new lines and player deployment and we end up in a situation where now not only is that first line negatively impacted from losing Kreider, but his changes are so bad that we end up with the entire forward group being impacted negatively. Honestly I'd try Gauthier on that line and keep everything else the same just because all the other lines were working pretty well and that move will basically have the least amount of reverberation across the entire lineup.
