A few questions about factions

[Ponge]

Greetings.

I am not posting this to Help and Support, because I do not really need help in this question, but I'd like to discuss possibilities, limitations and opportunities with those who are more deep into Disco and could provide me with advice. (And also not flood not get... flooded.)

I recently read a "draft" of an unofficial faction, which tried to horde all kinds of different factions under one tag. I know the rule is one ID allowed for a tag, but can there be an inRP justifiable exception, which does not get sanctioned?
Here is an example:
Indie DSE and Gateway players create a mining and shipping group (respectively) to ship platinum ore from Alberta to New London. The DSE ships mine the ore, Gateway ships haul it (DSE could also haul it, but that would make my example obsolete). They call this group the Alberta Division.
This way, is it possible for them to use the same tag (AD| for example), as their work/goal/purpose is basically the same, despite their ID is different? They have to team up becuase the two tasks cannot be completed by the same ID-d players (Gateway can't mine, and for this example, let's say DSE can't haul).
