Developing custom reports on Power BI with Dynamics AX 2012 R2?

Hii,

We want to use Microsoft Power BI for our Dynamics AX 2012 R2 Data Analysis, Reporting and Visualization.

I have following questions,

1. Can we connect Power BI Desktop with Dynamics AX 2012 R2 database? 
2. As you know, we have lot of AOT queries in AX, can we design same queries and relationships in Power BI?
3. We have SSRS reports in AX, some SSRS reports using AOT queries and some using RDP classes, can we get the same results in Power BI?
4. We have some reports, that are using complex stored procedures, how to manage them in Power BI?
5. SSRS reports show live data and transactions, does the Power BI show the live data?

Please guide with your experience, because its a big step for us to move to Power BI.

Thanks,
