Yes, but such proxies will likely require authentication with a Google account, and Google will keep an audit log to prevent "abuse". So at best it works out for maintaining somewhat persistent nyms for well-scoped purposes (that you make with a burner SIM or buy from someone who did), but not as some panacea for Internet privacy. This is of course assuming that the roadmap for these proxies isn't tied into their push for remote attestation ala "Safety" Net and WEI, in which case your "nym" becomes the entire device.
