Alright.
I managed to import model and texture of Lucario's Aura Sphere, and attached it on his Warlock Punch (on v2.3 Sword Ganon). The Sphere Model and Texture did come out nicely (almost looked like Mewtwo Shadow Ball), but there's this light flash at the end of the sphere animation, that flashes the whole stage or front of the camera which hurt my eyes. Since i attached it on PtcGanonMajinken, PtcGanonMajinkenHold and PtcGanonMajinkenFlash, the ball came out on their resp bone point, and it flashes 3 times during the warlock punch. As I tried Lucario Aura Sphere, it did come with some blue texture or gfx, what Warlock Punch did lack of.(Gonna check PSA for External GFX)
Since i used v2.3 which do have fake projectile Warlock Punch, The Aura Sphere did follow it as well. (the Ball position placed weird after the end of animation, which is probably bone position as well as fade timer. Can be checked through PSA)
However if attached to PtcGanonMajinken, all 3 stances will use on Warlock Punch external gfx (at least what i think so). Otherwise PtcGanonAppealS (which I think it his Side Taunt- the knuckle effect pose), can be used for his Magic Ganon, if called out File=21, Graphic ID=11. (Gonna check out more stuff and somehow delete this flashy light effect.)
Well it did work for his Side-taunt. :D
Here's a video for it just a few minutes ago:
