You can create an action profile for the same. When the Status in opportunity changes to 'Won', the chance of success also changes to 100%.
Use this as 'Start Condition' in your action profile. U can use Condition, 'Chance of Success' and equate it to 100.
Use Method as 'Copy Document' and in parameters use the tx. type which u want to the follow-up document.
I have tried this and it works....
Let me know in case you face any issues.
