The AKSZ framework constructs 2D sigma models in the BV formalism. Is there a generalization of the AKSZ approach to higher spin?
I am not sure exactly what you are after, but the combination of keywords brings this article here to mind:

Abstract: Vasiliev’s higher-spin theories in various dimensions are uniformly represented as a simple system of equations. [...] The proposed system of equations admits a concise AKSZ formulation. [...]
