Yes, if I understand your requirements right.

AFAIK, any dhcp range which, after applying subnet masks, matches any
configured address on the interface where the dhcp request arrived,
will be used.  This is after consideration of any "net:..." tag
matching being used to restrict distribution of those addresses.
