There’s a blog post on contactless payments in /e/OS here, which talks about options without Google Pay. It’s written by the guy who started /e/OS, so it should be a decent source.
My guess would be that Google Wallet is so embedded in Google dependencies that you’d pretty much be back at stock Android by the time you get it working. But I have no personal experience, sorry.
