Selah audio designs?

Sad to hear about Rick's passing. He designed some speakers back in 2007 for me. I was wondering if anyone knows who still has access or owns his designs? I'm looking to build some speakers (RS180 + 27TDFC) that he had designed that tonally match the ones he designed for me (RS150 + Peerless HDS). Does anyone still sell his designs or have access to them?
