How to access other PW site data in a multisite multi-DB install?

[hellomoto]

I know you can include the API for a PW install elsewhere by including its index.php file, but what about when you have a PW /site and then a /site-something directory with another one where you want to query pages from the /site ? I guess REST would be one way but is there any way to bootstrap the other site's data directly via the PW API, like its $wire or $pages assigned to some variable?
