It is possible, but I'd definitely recommend you don't try. Buy a 200 string of lights. There's a very good chance you will write off the two 100 strings that you want to join. More expense than you'd bargained for. I've 'hacked' a few light strings in the past and the hardest part is identifying where to cut and where to solder the joints. LEDs are wired in a series/parallel configuration and even the small light strings are a nightmare to unravel in order to identify the correct place (two wires) in which to make the joint.
