Untested, but most likely no. All downloaded content is dependent on your PSN account. I have a US version of the Vita version on a EU/UK account but I can't get any DLC from the store. However, game updates are delivered for the Vita version due to its nature, but I'm not sure that's the case on the PS3 version.
