For all of you looking to merge project Tasks, look no further. 

Here's a free module for Enterprise and Community:

Enjoy, and feel free to fork on Github ;)

Could a module be made to merge tasks?

I would really like to know because I too need such a module.

Hello Geetha,

Tasks can not be merged on the basis of their similar characteristics or data in odoo.

Thanks.
