housing hamsters that were not raised together

Question
I made the mistake of getting two pair of hamsters that were from different litters.  I soon found that this was very dangerous and purchased a different cage and am now housing them separately but this is getting to be tedious.  Is there any way to get these 4 hamsters aquainted with eachother so they could eventually live in harmony?  What would you recommend, if it were possible, would be the steps to get them to live together?  
Trying to make my life easier and I want them to all play together, any help would be great.


Answer
Dear Veronica,

Unfortunately there is no way that I know of to have them live together. it is possible, i suppose if you let them play together for a long time they may become acquainted, but living together would not be a good idea.
hope this helps!
sincerely,
Sarah
