How to connect to multiple Mongo dbs for an angular-meteor app?

I would like to try out the Angular-Meteor (Angular 2) for one of our projects which we need to connect to two or more existing mongo dbs, all using kerberos authentication. I found this post about “hacking” in Meteor itself: http://stackoverflow.com/questions/20535755/using-multiple-mongodb-databases-with-meteor-js. Does anyone know there is a way to do that in Angular-Meteor, preferably not hackish one? Thanks a lot in advance.
