Since we know that Courtney and Alison are twins in the novels, technically Spencer and Alison/Courtney would not be related by blood. Spencer and Jason are only biologically linked through Peter Hastings. Alison and Courtney biological parents would be Mr and Mrs DiLaurentis logically.

But to answer your question, they would be kinda related in a weird twisted way, just not in a logical biological way :)
