Yes you can connect pretty much anything after qcb+P e.g. qcf+P, hcb+K, qcfx2+AC SDM, run up dp+A, run up dp+C SC to qcf,hcb+A DM or even run up and start a new combo with c.C.
His qcf+C~A HSDM is notoriously hard to do consistently, but it does have the added bonus of being unblockable compared to the other HSDM input.
