1. Doing that is practically impossible if you dont know the code through and through. I wouldnt estimate it in days, but rather in months.
Then again, why does your bos doesnt want to run MyBatis? We use it compeletly hidden, and you never get to see it when working with Activiti.Furthermore, we have excellent integration with JPA if you want to store variables which are JPA entities.

2. Activiti is a standalone framework. Alfresco is not needed at all.

Eventually this is a very interesting point and actually from previous JBPM 3.x experience - we had the same constraint and requirement.

We wanted our JBPM sub project to 'stay' on top of the common persistence provider of the overall system thus we were re-using our hibernate.cfg.xml on the JBPM sub project.

Actually the question would be how transaction handling would be efficiently managed since a workflow will be manipulating resources - outside of it;s project scope. eg call EJB's, Facades, alternate the business domain model.

Any hints? (nice question by the way)

JTA manages the transaction 'issues' perfectly. Just make sure Activiti and your project are configured to use this. So it is as Joram states a 'non-issue'

Indeed, JTA transaction mgmt or a spring transaction manager does exactly that job.
