How can I duplicate the Leads Module?

1. How can I duplicate the leads module, creating another link on the top menu bar? 
- We have different type of leads that need to be separated into different modules. Both types can be converted to accounts, but each type needs it's own fields. In other words, we need a all the features that are present in the Leads module (email tempting, option to convert, option to create custom view, etc), but under a second tab. 

2. How can we move records from Accounts that were closed into another segment under Accounts?
- Accounts don't always stay accounts, some go, more come. How can we remove the accounts that cancelled their membership from the Accounts module, but not remove them from the records.

Thank you!
