    Any number of vents may be revented back into the main vent, however, there is a problem. Chapter 14, ( Vents and Venting) Section 1403.3 ( Main Vent Stack) of The Standard Plumbing Code states "Every building in which plumbing is installed shall have at least one main vent stack, of not less then 3-inches in diameter, which shall run undiminished in size and as directly as possible from the building main drain through to the open air above the roof."

    If 2", is indeed, your main vent your house is out of code. Vents and vent sizes are there for a reason and the code should be complied with.
    Sorry to be the bearer of bad news. Regards, Tom
