Man this is quite a late reply, but any idea on the vid you’ve seen this done in? Or who you’ve seen do it in-person? I can’t really recall such, but I doubt it isn’t possible given some quirky timing and height adjustments…
side note, I’d appreciate some neg rep too…tryin to fill my K-groove and best phrostbyte 
(seriously…)
The other ones require more patience and focus, which I lack (ROFL)…
But seriously, wait til about the 20th hit or so to assist, then go for aerial, snapback, etc…
just because you change the subject does not mean you can be offtopic. this thread is strictly for psylocke infinite, not your crappy post.
the rest of your post is just stupidity/no sense/total changing the subject (because you’re a stupid ass and want to to draw attention away from it)
Also, with her infinite, try to cross over w/assist (Sentinel , Storm).You know her roll back motion, where you hold hk< then>?, that move combined with an assist may reset it. Its possible to reset the infinite (I think) once youve crossed over to the other side.
