Can we join 3 Object variables inside the package?

Hi,

I have a critical requirement.

I have 3 object variables inside my SSIS 2012 package. They are like 'table' structure . 
Eg: First 'object' variable has fields like EmpID,EMpName,Empsalary
Second 'object' variable has fields like ProductID,Productname,product description
Third 'object' variable has fields like SalesID,salesdesc,salesamount

Now can I join these 3 object variables like we do for normal tables and pull the fields from these 3 'object' variable output into another Object variable like 'var_output' . Becasue I may need it to give 'var_output as a input to ForEach loop ADO Enumerator? 

Please help!
