Based on my research, you may use KMS and ADBA at the same time and ADBA uses the same host key that are used by KMS.
KMS and ADBA not mutually exclusive.
Does "stand-alone" just mean out of the domain but those KMS clients could connect to KMS host?
For those previous KMS clients , they will still connect to the KMS host regularly (For example, once every 180 days) as before to resume activation process. So, you need to maintain the connection between the host and the clients.
More informtaion please refer to "Active Directory-based activation of Office 2013" and "Active Directory-Based Activation Overview".
