Hmm my honest opinion right now is that this will work if you have the balls to pull it off.
This opener is definitely for daygame, where values work differently. During daygame you don't need to neg and DHV as much as compared to clubs.
It just needs a little bit of reframing, thats all..
PUA: Hi, are you as stunning as ticklish

?
HB: *Laugh* Yes/No/Maybe
PUA: Great, thats just about all I need to know..., but right now, I need to know where you tickle at?
(Notice that I treat all the answers as the same simply because I didn't give them the chance to say "no, I am not ticklish".)
HB: I tickle at blahblah...
PUA: Seriously? *Confused look*
HB: What?
PUA: No, you are like the first person I've ever met who tickles at blahblah!?

Move to a routine or stack another opener.
Later on you can tickle her from one of the spots she mentioned just to make sure she was serious about it
