I understand that you want to show all the tasks in multiple site into a single task list.
Here are my suggestions :
In this way you can display all the tasks in a single web part ,but you cannot connect this web part to Outlook .You have to manually connect task items to outlook one by one .
There is another workaround
You can create a task list to save all the task items .And create an event handler to copy the task items to this new task list when the user creates\update the item. Then you can connect the new task list to outlook .
