First, even if this particular design isn't fitting or wanted by the FR team, I still say it'd be cool to have a two headed bab or fifty in your lair.
I have got some doodles though.

[previous EDIT: Forgot to mention this.]
I had a thought with these guys being able to eat both meat & plants, with some lore in there that one head eats meat, & the other eats plants. Both can live if only one eats, but the head that doesn't have food will get very grouchy. Separate digestive tracts means that the one without food has a very angry belly on their hands.
[previous EDIT: Thanks to @Vaemethius for this snippet of lore idea]
A way to tell gender with these babs, is to look for which head is the dominate personality. Is it the meat eating head, then that dragon is most likely female. The plant muncher? You got a male on your hands then.
[smaller EDIT: I'm going to work on some more art of these guys this weekend, so look forward to that maybe. XB]
Thoughts? Suggestions? If this is popular enough & I have any spare time I may add some colors & markings to the lineart in the corner for more examples. XB
[EDIT: More images!]

Leggssss. I imagine they're probably leapers & diggers more then fliers.

Wings...yeah they're a little weird, but I wanted something that'd stand out from the other FR babs currently, & was aiming for a more insect-ish shape with them, while still being...not...bug wings. XB
[EDIT: AGAIN! 8D]

A possible pose...or just me wanting to push what this design can do pose-wise. Because they're meant to be fairly short bodied babs, with long tails & somewhat long necks. This little one...is probably gonna crash if they don't look where their going. XD
