I think installing the apps via Aurora Store and running them should definitely work. There might be issues with syncing them to your Google account though. You can add the account via MicroG (preinstalled) but since I have no experience with running GApps on /e/os I can’t attest to how well this will work, if at all.
You can install Lineage OS and add GApps though, if you’re looking for a custom ROM but need extensive support for Google apps.
Might I ask what’s your incentive to switch to /e/os? Installing Google apps kind of counteracts the privacy aspect.
