possibly. I know you can on the ps4, inside of a cache folder iirc. on the ps4, it's like several png and dds files of various resolutions for the avatar. I've never looked into this on the psv, but if I had to guess, I'd say the avatar is probably located on ux0 or ur0. an avatar you install - I don't know. I don't think pkg2zip, which is the package decrypter app, is compatible with avatar packages. I've never looked into that either though. interesting question, but this is for custom avatars, not necessarily official ones. this might be undone with a rebuild of the database.
