If by "don't see each other" you meant that there is no connection object,
then yes, you can manually create one, especially given the fact that you
said you plan to demote the other DCs. BTW, the object is only created
automatically when it is considered needed. In your case, since the LABDC is
already connected to the other 2, another one to DC3 is not considered
necessary. That's why it wasn't created. If you demote the other 2 DCs
without manually creating a connection to between DC3 and LABDC, you will
see that it will be automatically created in due course.

Install DNS, create a corp.lap zone as secondary and point to one of the DCs
as master. After the zone transfers over, change it from secondary to
AD-integrated Primary zone.
