Just make a new Google account. It's not like you have to fill correct info and you can make two accounts with same phone number (at least I could ~1 year ago).
Maybe I am too reliant on my gmail account.
Ding ding ding!
I literally have same phone number at both, so it would be easiest thing in the world to add verification for uniqueness of the phone number.
It's not like I am making tens or even thousands of accounts or doing anything nefarious with them. Just having my "official" account and "throwaway" account.
Can google ban happy ban me? Sure, if that happens, it happens. I lost access to my email before (small national provider from days before the internet was big, it just stopped working one day). But that can happen anyway, but I don't see any policy that would suggest that (at least nothing in first page of google suggest that).
