FIM Reports using scripts

I am trying to generate the default FIM reports which we get from the Reporting tool. However, the client does not want us to use or install the tool and we have to use some form of scripts to get the work done. I am looking for the following reports:

1. Group Membership Change
2. Set Membership Change
3. Group History
4. Set History
5. User History
6. Request History
7. Management Policy Rule History

Can someone help me with the scripts or point me in the right direction for it? Thanks!
