I agree with Match you can just swap the emitter with great results. Here are 2 threads I created that show exactly what you need to do.
If you have trouble prying the emitters off try freezing the pill then prying them off. If you have trouble getting the drivers off try using an exto knife and a little heat and prying.
Nanjg 105c drivers are perfect for this swap, Shiningbeam makes it easy with presoldered wires and mode selection already taken care of.

If you get stuck post up and we will help.
Edit: I see you are not in the states so these drivers are more cost effective they have them in singles if you don't need 5.
