It should just work.  I can't say it will, for this particular combination,
but generally it works fine.  You can try to join and see.  There should be
nothing bad happening to the existing DCs.

Personally I'm a bit cautious to use a .0 version (4.19.0 is a first release
of 4.19 ever, and 4.19.1 does not count as it is an un-planned security-only
bugfix release), but this might be just me. In the past first releases in the
next series did have issues.
