OK. Assuming that "put all of the fixed infrastructure on one single main-office 
LAN"
was even workable, what address block would you use for that LAN?

IPv6 is not a viable solution at this time; partly due to lack of experience
with IPv6, partly due to just having way too much equipment from way too many
vendors that still doesn't/don't support IPv6.

I wish IPv6 were viable; even using an unroutable IPv6 subnet would realistically
work, because (still) basically nobody else is using using IPv6. And, given the
status of the IPv4 pool, IPv6 viability is way overdue; doesn't affect reality.
