Hold on, Christopher ... I thought the previous Rayna prototypes were just earlier casings for her mind, allowing her the illusion of physically growing as her mind developed. Hence the reason we see labels like "Rayna - Age 14" etc.
I've toyed with the idea that Soong was Flint and that Data was just another variation on a theme for him. I know, I know, McCoy said the man was dying now that he'd left Earth, but Flint himself said earlier that throughout his lifetime he'd pretended to grow old, die, and move on many times. I'm pretty sure a man of Flint's accomplishments would be able to deceive an old country doctor, too. And towards the end of "Brothers", his work with Data coming to an end, he's pulling the same stunt. Poor old Soong so old and feeble, he's sure to pass away any day now. Or so Data will tell everyone.
