Yes, this is possible. You will legally own the account, also the account is searchable in the mainland of China.
Here is an example in Australia- [Sydney airport].
As we all know that you can create a WeChat Official Account with an oversea business license on https://admin.wechat.com/ .
Also, these kind of accounts are not searchable in the mainland of China, it means that you can only target the local Chinese. Then how did Sydney airport make it?
Sydney airport had been invited by Tencent.
Bad news is that the inviting function has not opened to public yet, it’s still under Tencent’s inner test.
Good news is that you can find agents on the market help your business get invitation from Tencent. The agent will require thousands AUD for service fee. It will cost you several months to get invitation and approved.
It’s hard to predict whether this function will open to public soon.
In my opinion, this is not a business issue, but a political problem. Walk in Tencent’s shoes, it definitely want to be an international brand. But it is also a Chinese entity, it should be cautious to help entities from other countries get access to Chinese citizens’ social information.
