I did it recently. I ripped off the sample PC's from Paizo's Pathfinder adventure paths. The characters are so well done, my PC's assumed they were actual PC's from my other campaign (I run an email and a live campaign, with some overlap of NPC's and references to each other's parties).
The ones I chose were all from Pathfinder 3 "Hook Mountain Massacre" (to get the appropriate levels):
-- Valeros the Fighter (party leader)
-- Seoni the Sorceress
-- Kyra the Cleric
-- Merisiel the Elvish Rogue
-- Harsk the teetotaller Dwarvish ranger (actually from Pathfinder 9 "Escape from Old Korvosa")
The PC's ended up making a deal with Valeros' party and becoming allies.
The other party I'm running will likely go into the Shackled City Adventure Path soon, and face off with the Stormblades.
Note that Valeros' party doesn't have a name . . . I've never had a PC party wth a name, so it seems unnatural and pretentious to us to name a party -- perfect for the Stormblades.
