Maybe it's a good idea but only for the additional fender indicators.
I tried to install LED's on my Demon (front and rear turn signals), and it was a complete mess.
Not sure what kind of LED's you used, but I upgraded my Duster without issue. I ended up using the special LED flasher unit for both turn signal & hazard. I had to put standard bulbs in the brake lights to make the turn signals work properly with the lights on. Weird, but that resolved it. I got my LED's from superbrightleds.com and the flashers from another source I don't recall. Do not use the flashers from superbrightleds, as they did not work for me.
