Minor Spoiler Warning for Shadowbringers, has to do with a minor-main character enemy (doesn't really mess with the plot if you know, but if you wanted to be surprised to combat and such, a "ooo" "aaaah", then consider caution for the following). A non-spoiler hint if you already know this minor spoiler would be if you've come back Eulmore/met the dwarves (dwarves not a spoiler because they were in the live letter lol).

This character uses his minion and absorbs them to both change appearance (equipment really) and gain a host of new skills, while not really a morpher job as described in OP and I would love to see it taken farther (as Dualgunner and I were sort of going off on how cool the devil trigger in DMC is lol), I still felt it akin enough to be like "oh hey look, that's neat and sort of morpher like". Might say its especially morpher like if you take FF morpher at a basic description of "uses souls of monsters" :3. So this guy's morphing slight appearance is in that vein of desire of the thread but the end desire is and would still be a complete change like the Dante DMC, Vincent FF7, and etc examples.
Also might add that the character has a bit of beastmaster elements so they may be used in that topic as a talking point too, but this thread really isn't about that job :p.
Definitely was thinking something similar~! Although of course I mostly just throw stuff out as basic concepts since I don't think SE would or should just 1:1 take an idea (trying to encourage/inspire/spark something :D). Though as what you described I would love it if SE tried to make a job like this have a shifting/dynamic elements to their rotation with value for each form, instead fixed choices or a series of shape 1, 2, 3, rinse and repeat. How fitting for a shape shifter to have a shifting rotation ;).
