As there will no doubt be a stampede to get these new Luke ANH sabers converted to Luxeon in order to be battle ready and have removable blades I'll save people some research time.
There was a time when the Custom Saber Shop sold a kit to convert the fixed blade Luke ANHs to Lux (LED in the hilt, empty blade) but its been discontinued for years. They never developed a kit for the removable blade model due to lack of interest. CSS, Ultra Sabers and Ultra Force Sabers also offered a conversion service which would take your fixed blade saber and convert it for you for a fee. The only company to still offer that service for the Luke ANH is Ultra Force Sabers and it runs $120 (which given what a PITA it is to take them apart is a bargain IMO). The catch for them is they don't work on Master Replicas any more, there are very few 2007 Hasbros around and you look to pay $200 for one if you find it.
Ultra Force Sabers do GREAT work. Takes a few weeks but great communication and the customer service is excellent. Here's some pics of the Hasbro I sent them with an UltraEdge blade from Ultra Sabers and a custom blade plug from defconbird on fleabay:

Now, depending on what Hasbro's new "tech" for the Force FX line is (better not just be going back to fixed blades for chrissake) the new Luke ANHs should be no problem to convert, have the remastered ANH sound fonts that the removable blade versions have and be cheaper than old fixed blades to use as a donor.
Also, though the conversions reuse the plastic blade holder rather than having a cool machined aluminum holder like other models, I can testify to the durability of these conversions as my kids and the neighborhood kids take these out daily and duel with them... well, a red button fell off but epoxying in a replacement from The Graflex Shop fixed it right up.
