Ok this has been interesting. In the World Rugby website, I can find no reference to a Quick Line Out, there is a QTI and a normal, bog standard, run of the mill lineout. So it would appear that the 2 players from each team may only prevent the QTI to be taken?? Then the throwing team would need to wait till the Lineout is properly formed.
There should be 2 options available the QTI, if that's not on then a properly formed lineout. Unless someone can show me the Law for the inbetween Quickly Taken Line Out.
I will add, I suppose it depends if a) The throwing team have declared their intent to have a lineout shortened to 2 participants and b) would you allow them to at the last second increase the number of participants if they've not declared.
Plus just reading the LO Law it does state that the non throwing team Must have a play in the 5m area. This suggests that if QTI is not available the the throwing team must wait till the lineout is actually set correctly.

The player stands two metres from the mark of touch on their team’s side of the lineout and two metres from the five-metre line.
