I had an idea for a nearly identical deputize command back when I was exploring tribunal warfare and trying to find ways to get allied tribunals to actually be able to truly come to one another's aid with their resources.
Auto-at-war-Tribunal-attacking guards happened after I did that. Sorry, everyone, that was totally my fault.
I pitched deputize to Dulrik months ago in a more serious medium and there is a possibility I heard someone say it was a no-go.
Tribunal members are executive, not legislative, and the SK legal world does not afford many non-enumerated powers to its tribbies save for the inalienable right to gank. In the vision I was given, they are the enforcers of law and hardly, if ever, the creators of it.
This is why I was largely disenchanted with the whole thing. There were too many obligations with few rewards save access to spells. I wore bondage roleplay bracelets and got to hold a tactics horsewhip as a reward. The experience I expected was far different from the experience intended for me.
