This is actually a good question. I think that if you were an afc when you first met a girl,then you don't see her for a long period of time,and when you do see her again if you're no longer an afc,then yeah,I think she could be attracted to you. However,I think there are a couple of conditions that have to be met first:
First of all,I think it depends on how long the two of you knew each other while you were an afc. If it was for a long time,like maybe 3,4,or 5 years,then it would be harder to do.
Another thing is this:You would have to go a long,and I mean a looong time of no contact/not seeing her. And I mean like you moving to the other side of the country so there is absolutely ZERO percent chance of the two of you bumping into each other.but cause if you do,it starts all over again. This is basically the same situation as being in the friendzone. It's identical. If she met you as an afc or you fell into the friendzone with her,the process of trying to undo the damage is possible,but it requires so much time,so much effort and energy,that it's just not worth it. It'd be easier just to move on and meet someone else. I mean,who wants to put at a minimum, 2 to 3 years of no contact and avoiding a woman,simply just to have a "chance" at dating her?
Even if you do put in the time and effort,and you are able to change the way she sees you,all that does is put you at square one. You still have to generate attraction in her,build comfort,avoid the friendzone trap,avoid activating her ASD/anti sl*t defense,avoid or minimize the chance of flaking,and so on. Nobody wants to go through all that. I know I don't.
So yeah,I do believe it's possible to make a woman attracted to you if you were an afc at the beginning,then after some time has passed,you meet her again no longer being a wimp. Buit it's a heck of a lot of work.
