I have one for my son and planning on modding it. For his height there are some pretty inexpensive "non-brand" lightsabers on AliExpress or Amazon that I plan on buying for the blade and electronics/LED. I am going to replace the saber blade with a more realistic version.
Next I plan on repainting and weathering up the device.
My plan was to have this done before March so we could all go to Disneyland Season of the Force but now with the security changes I'm shooting for April at Legoland Star Wars Days.
