They made a blatant attempt at the opposite idea a couple of years ago.
They cut Epcot's regular closing time from 9PM to 8PM only on Epcot's PM EMH night.
That meant that IllumiNations ran at 9PM every night (as it still does)
EXCEPT on PM EMH night at Epcot, on which the IllumiNations show ran at 8PM.
And, on that night PM EMH at Epcot ran until 11PM for resort guests.
Not exactly a "late event."
That plan didn't last very long.
Just a few months.
Same thing occurred at AK where regular summer closing time was 8pm except on EMH evenings when the park closed artificially early at 7pm resulting into 'extra crowded hours' of 7-10pm.
