One lipstick PU per string and parallel to it = 0.64' (width of the baseplate). Six of them would take 3.84' = 9.76cm.
String spacing in my Strat with lipsticks is of approximatively 5cm under the mid PU. It leaves enough space for 3 lipstick PU's, not six. i'd rather think to 3 rails PU's with one blade per string.
Regarding the "sensing windows": the effect of its width would be a drastic diminution of harmonics, as shown in the simulation below (black line = fundamental & harmonics of a neck PU perpendicular to strings. Blue line = the same with PU parallel to strings. Thx to don Tilman for his useful applet allowing to do this :

It would sound very muddy and with lipsticks, mud would be aggravated by Foucault currents. Unless the PU's would be wired in parallel, in which case they would sound very weak - without solving potential problems with "stratitis" and shortened sustain due to magnetism.
Regarding lipsticks in general: they are low inductance pickups whose response is softened by Eddy currents. Their interest is in their chime IMHO and IME. Anybody who would find them too soft and/or weak can pair them with a 500k volume and a no load pot: that's what I have and my Strat with lipsticks does not sound weak (at least its lipsticks are not weaker than its CS69 bridge PU). If it's too bright, just add a low value cap (470pF to 1nF) from ground to hot - or plug the guitar through a long cable...
FWIW: morning post before coffee. Have a nice day!
