I was afraid I would encounter issues importing another file into the same
database - have not attempted it yet.  I'm certainly willing to share any
info if fortunate enough to get things to work.

I've read that updates are supported, but I haven't looked into that aspect
yet.  The thought had crossed my mind that there may be issues with only
needing updates for a small area such as one state. The up side of a small
area is that it's probably not a huge deal to configure a new DB and
re-import the state file again.  I may look into scripting that process.

Speaking of APRSISCE/32, if I were to set it up in Wine on the same laptop
it should be able to access the local OSM tile server as well.
