The Bracers are really good at offloading their work onto just about anyone regardless of faction. Technically, they have already done this with an Ouroboros member too, albeit a Manchurian agent.
Funny thing is that Falcom did had idea for Enforcer protagonist in Calvard arc. But felt it would be too underground so they came up with Spriggan someone who can work both openly and in underground. Wonder if Ash would become one in Erebonia.
