I would seriously consider secondary DNS server(s) doing zone 
transfer(s) at each remote site /and/ *configure* *the* *secondary* 
*server(s)* *to* *forward* *updates* *to* *the* *primary* *server* at 
the central site.

This would offer some autonomy for both DHCP /and/ /DNS/ in the event 
that the connection to the central site was unavailable.  Admittedly 
DDNS updates might fail during such an outage, but clients would still 
be able to get an IP /and/ /query/ /DNS/.

I know that this isn't quite what you have described / asked about, but 
it's what I would consider for such a multi-site installation and I 
believe I would be remiss if I didn't at least ask "have you 
considered....".  ;-)
