In a world where it is acceptable to be glamoured in a full Moogle/Pig suit, a bathing suit, Santa, a reindeer, etc. it is not possible for us to mix and match job pieces. Is it time for this to finally be allowed? It would open up a lot of glamour possibilities.
The one excuse I could possibly see for not doing it is PvP, where it might cause confusion for who you are attacking, however I would immediately point out the above examples (besides it being obvious anyway). If an entire team glamoured as Moogles you wouldn't be able to tell the difference outside of the obvious ways anyway. So I do not think that is a valid excuse to begin with even though I bring it up.
Instead here are some reasons why it should be allowed:
/////
We already have actual job swapped gear models/recolors.
In fact the most recent dungeons are an example of this besides the numerous other examples of recolors between different job types. This is usually pretty normal between Fending/Maiming, Healing/Casting, Striking/Aiming but for some reason taking it one step beyond is "too much" yet the other outrageous glamours are an acceptable fit in the world.
Examples:
- Tank Gear = Fillibuster's Helm of Fending / Rakshasa Mask of Fending
- DRG Gear = Royal Volunteer's Helm of Maiming / Rakshasa Mask of Maiming
/////
NPCs have mixed gear "glamour" already.
Notable Example = J'olhmyn:
- Cobalt Trident = DRG
- Filibuster's Gambison of Scouting = NIN
- Filibuster's Gloves of Healing = HEALER
- Filibuster's Trousers of Fending = TANK
- Expeditioner's Moccasins = ALL
That is FOUR different job types represented in their outfit. The function is clearly there.
/////
You have already removed the uniqueness of the major NPC's look by allowing people to buy their outfits through the Mog Station. You are basically saying it is acceptable for major characters to no longer appear special even compared to the most basic of side quest characters like J'olhmyn. You can choose to look like Aymeric no problem, but J'olhmyn is unheard of. This seems odd to me but understanding cause $.
/////
You could keep a restriction on the job specific artifact armor to at least maintain that identity for the jobs intact, basically no blue "artifact" pieces can be used on a different job glamour.
If there's any ounce of job integrity left considering the other glamours available, at a minimum this would seem like a reasonable exception if everything else was allowed.
This way any excuse of wanting a Paladin to be a Paladin is passable if we ignore the fact that you can do everything else under the sun except look like a caster, healer, aiming, or striking, since looking like maiming is acceptable already or a pig...
/////
Before opening the flood gates, maybe test the waters by allowing us to at least glamour within the same "types" as mentioned above. Fending+Maiming, Healing+Casting, Aiming+Striking. They already share gear models for some pieces, but this would at least open up some color swapping possibilities while providing some new options on non-shared models without going too far into those other job types. If we can't have everything, maybe this would satisfy people until it becomes an acceptable option in the future to open everything up.
/////
From a business perspective it incentivizes people to get more gear for more glamours. More gear means more slots needed. More slots needed means more retainers. More retainers means more money. More money means more profits for you.
More gear means more time. More time means more subscription time. More subscription time means more profits for you.

More glamour options, obviously, but it's the most important.
