Hi Jason,
Recently a colleague of mine informed me there is a new GPO tool that was released just this year. It has a really cool feature where it can read registry.pol files and spit out a plain text file (among other things). Check it out, it may save you some pain! 
LGPO.exe v1.00 - Local Group Policy Object utility
LGPO.exe has four modes:
- Import and apply policy settings;
- Export local policy to a GPO backup;
- Parse a registry.pol file to âLGPO textâ format;
- Build a registry.pol file from âLGPO textâ.
To apply policy settings:
LGPO.exe command [...]
where "command" is one or more of the following (each of which can be repeated):
/g path import settings from one or more GPO backups under "path"
/m path\registry.pol import settings from registry.pol into machine config
/u path\registry.pol import settings from registry.pol into user config
/s path\GptTmpl.inf apply security template
/a[c] path\Audit.csv apply advanced auditing settings; /ac to clear policy first
/t path\lgpo.txt apply registry commands from LGPO text
/e <name>|<guid> enable GP extension for local policy processing; specify a
GUID, or one of these names:
* "zone" for IE zone mapping extension
* "mitigation" for mitigation options, including font blocking
* "audit" for advanced audit policy configuration
/boot reboot after applying policies
/v verbose output
/q quiet output (no headers)
To create a GPO backup from local policy:
LGPO.exe /b path [/n GPO-name]
/b path Create GPO backup in "path"
/n GPO-name Optional GPO display name (use quotes if it contains spaces)
To parse a Registry.pol file to LGPO text (stdout):
LGPO.exe /parse [/q] {/m|/u} path\registry.pol
/m path\registry.pol parse registry.pol as machine config commands
/u path\registry.pol parse registry.pol as user config commands
/q quiet output (no headers)
To build a Registry.pol file from LGPO text:
LGPO.exe /r path\lgpo.txt /w path\registry.pol [/v]
/r path\lgpo.txt Read input from LGPO text file
/w path\registry.pol Write new registry.pol file
