Now I've been tasked to look into Signing our AD implementation. MS has their own version of DNSSEC for their DNS but my question is would this work, at all?

The only solution I can think of is import my BIND keys into Active Directory DNS. I don't know if that is doable at this time.
With a private version of a domain, you should not need to worry about a DS record in the parent. Just make sure your internal caching servers not only can find the internal version of your domain, but also can validate the signatures therein, most likely using a trusted or managed key specific to that internal domain.
I'll not try to get into the specifics of using MS DNS for this purpose because this is not the right forum.
