Is it possible to combine AR with MongoMapper/MongoID?
If so, are there tutorials/documentations for this?

Yes it's possible. Can you please be more specific on what you want to achieve? It's even easier if you use Rails 3 because mongoid and ActiveRecords uses ActiveModel as the interface.
Yes, it is a piece of cake. There really isn't anything special you need to do, just make models with the different adapters accordingly. This is an example Mongoid document:
class Project
include Mongoid::Document
end
For comparison, here is activerecord:
class BillingEntry < ActiveRecord::Base
end
Just make sure not to mix them up. For example, don't include mongoid on a class that inherits from ActiveRecord::Base. I recommend Rails 3, as it's probably going to release this week, and the RCs have been really solid so far.
