Sounds good and I'm VERY jealous of the technology. If the inks used are watersafe (laser/litho) then you could see if lightly misting the fabric with glow in the dark hairspray or cheapy dollar store woolight handwashing clothing detergent (cut it 50/50 with water and put in a fine mist spray bottle) might kick up the glow (UV reactions from the phosphates in detergents are why your white shirts GLOW bright in blacklight).
I would also make sure that the blacklights are real ones - not those terrible old school looking bulbs you see for a few bucks and get dangerously hot. Either the long tubes or the compacts that are curl or U shaped are truly blacklight bulbs.
Depeding on the rest of your decoration outside, you could do some uplighting in between the window using LED colored spotlights. I love purples and blues and green but of course orange is traditional and would look really nice with the blueish purple effect of a window display using blacklights!
