You've certainly given me something to chew on but as I think Flowey/Asriel's reset abilities came from still having Chara's soul inside him Flowey can't reset due to Chara leaving him for Frisk as a host and as the six souls are most likely able to move on Flowey has no access to human souls to regain the reset power.

Plus as I don't think Flowey is soulless as he believes he is he would also not have any desire to.
