Sounds like a sweet idea to me..
Could be fun too and yes, a great oppurtunity for new patches!!
We have been brainstorming about that also over here in the netherlands( al ot of sandtroopers over here..at least 4..ahum), maybe forming a squad with sandtroopers from the Nordic Garrison or the German or the UK, but precincts sound even better.
I hope that there will be more enthousiasts for this ...
