But I would still  lose my DHCP, internal DNS, NFS, NTP, multiple user
account passwords, printer configs, crontabs, etc., etc., etc.; if I
did this.   Even though I only have a few machines, I don't run them
as if they were single-user Internet browsing machines.

Apparently not always true.   This guy apparently wrote GPT fdisk:

http://www.rodsbooks.com/gdisk/

and has a page which describes how to do it (when it is possible):

http://www.rodsbooks.com/gdisk/mbr2gpt.html

He also discusses using Hybrid MBR/GPT partitioning on other web pages
as well as UEFI booting.   Looks like a good resource overall for
this.
