Expand Free Company Crest and allow it for personal use

Yesterday, I went to see the free company of my guild to remove one crest from my gear, and noticed the crest (or emblem).

I didn't remember this feature because it's limited in its use, I mean, it's only accessible for high rank (or creators, don't know) of guild.

Since 2013, I didn't use it, forgot it, and still today can't use it.

So my question is : Can the Free Company Crest be allowed for personal use ?
The crest will be show on the personal informations of the player.
Otherwise, at the very least, implement it for the Squadron.

Bonus : SE could expand the Free Company Crest feature, and put them as rewards in various contents :)
We can imagine future crests inspired from primals, raids, dungeons, areas, cities, people, beast tribe, etc.
