Chris, Can't say I'm an expert, but I have looked as I am planning on doing the same down the road. I've found nothing that implies you cannot. In addition, up till at least 1969 Detroit was still building cars with split windshields (69 Dodge Sportsman Van) which effectively have the same encumbrance. And as Mahlon pointed out, many low volume commercial vehicles still do and they are generally concerned with DOT regs.I'm asking this from a completely uneducated standpoint here, but are there DOT regulations on the additional brace in the middle of the windshield? Anything to do with blocking the driver's view?
