Oh. Alec Tintagel in Artifacts Unbound is a former Ghost mage, and Jessa is a Paladin mage. Also from that book is a badass adept named Felicia McGuinness (a Tír na nÓg equivalent to a high-level Ghost adept). You could also use a lower-powered version of Thorn from Street Legends (the errata'ed version you can find a link to in Critias' signature) or his spyhunter counterpart (Again, in AU), Samantha Roth if you remove her social adept skills and powers. Some more combat adepts from Artifacts Unbound who would be models for Ghost adepts include the Leopard Guards, Veteran Combat Adept, Rory McGuinness, or the Duelist Adept—who has a power set similar to Talondel, the Paladin in the story in Way of the Adept.
Hm ... There are some tough customers in that book (That would be mainly my fault) and later campaign books. But you may want to start there. There are also some adepts in Jet Set that would be good models.
