Yes, I'd bet they can, and will. One of the advantages of ordering a plane factory-new is that you can usually specify exactly the equipment you want in it. And, the manufacturer is strongly motivated to accommodate you, with mods and LOAs (especially if you are willing to tell them that, without those accommodations, the deal is off).
I had a similar discussion at Sebring last week, with one of the S-LSA manufacturers. They essentially told me that, for a 20% deposit, they'd spec out the plane equipped pretty much any way the customer wanted it (within reason and LSA limitations). Of course, this buys you only a position in the production run, so you may end up waiting a few months to take delivery on your plane. In airplanes, as in cars, buying something that's already in the dealer's showroom is always quicker, and cheaper - but, you have to settle for whatever color is available, and whatever equipment is already installed.
