Can I add a brachoffice DC to a multiple branch single domain with connection to pdc in headoffice only?

We have a main office in Holland where the FSMO resides in a single windows 2008 R2 domain.
We have branch offices in 6 countries with one GC server.
I want to add a new branch office in a foreign country.
due to configuration problems in routing we can only connect to the headoffice where the FSMO recides.
The other branchoffices lack routing facilities so that they can not be accessed for the moment.
the routing problem will be solved but we want to install a dc in the new branch connecting only to the FSMO for now.
the routing problem can only be solved after a week or two.
Are there any reasons not to install the branch DC and wait for the routing issue to be fixed?
Or can I just go ahead and install the dc while other branch offices can not see it?
Any help would be greatly appreciated!

You can go ahead and install DC in branch office. If required you can create manual connector in AD site for replication.

There's no reason not to install it. Create an AD site for it, associate the site with the appropriate IP subnet, and create a site link between the new site and the central site. That should be all you need to do.
