I'm only using the Rx and Tx lines (do I need to have a cable with more than 2 wires?) so I was thinking of a smaller connector in the device (RJ11 for example) and providing a RJ11 male to DB9 female cable with my device, but I couldn't find such cable on mouser. Is this so out of the normal that I'll have to customize a cable for this application or do you know a manufacturer that makes such a cable (or one that uses similar small sized connector on one side of the cable)

There was an earlier thread on something similar to this.

Beyond what is available there is something else you need to consider
when using other connectors: what will people do? 

For example: if you use an RJ11 connector you have to be prepared for
people to plug your device into a phone line (can your device handle 100
+ volts AC?)

Other connectors have similar problems. I'm not saying NOT to consider
other connectors, only to consider how "inventive" people will be with
what you plug your product into.
