I kind of think the same though in terms of power level I dont think it would be good for Sanji to unlock ACoC later than Luffy and Zoro. ACoC is different from FS in terms of power level (its a straight up boost while FS is about dodging/evasion, one of a defensive maneuver you can say). Of course if Oda retcons the Power of Love to be some form of ACoC or Sanjis flame abilities being a form of ACoC then I can accept it. One way or another Sanji is bound to be above Prime Gaban who was an ACoC, ACoA (Ryou, he is flowing haki to the axe) and ACoO (FS) user.
Your visual appeal thing is correct, Sanjis strikes are beautiful, his combos indeed look visually better (better flow and choreography) than a big punch or a single sword slash, though I dont think the no touch version is an absolute requirement. Personally I wouldnt want Sanji to have black flames (I think it is too overused) and pure white flames against Sanjis thematic black pants would look better in the manga medium.
I mean the non-touching kinda the distinction tho to normal haki, and a larger range even to ryou. Oda already draws haki like ass, thats why half of this discussions happens in the first place. So if its not gonna use Coating, which is yes, a AP upgrade but also a range, what the fuck is even the point? Ruin the visual art with black lightning shit that looks exactly like armament and cause dumb arguments and ruin the art style of sanjis artstyle?
I like the white lightning idea, my only issue, or rather issue that oda doesnt gonna do that is because IJ already shits out White lightning as if he was enel at this point, which is gonna be stronger not weaker going forward
My hope/cope is at this point to be honest is Power Of Love is still its own thing like i wished for and he gonna combine acoc pol and Future sight into its own fighting style but that is what i wish for, its some prime cope realisticly it gonna be some dogshit "mouton shot extra coc" that gonna look ass
