Sure, but USF is still going to be the only park with designated facilities for hosting walkthrough/house type attractions if you want the event to include those like the survey indicated.
USF could definitely host a festival/con event that's included with park admission in April-May, but I don't see any availability for more hard ticket events at USF because:
Sept-Oct is HHN,
Nov-Dec is Christmas,
Jan is open, but too short to set up anything major,
Feb-Mar is Mardi Gras,
April-May is Grad events, and
Jun-Aug is peak summer season and major prep for HHN.
Maybe IOA could do a hard ticket event in Jan-Feb though?
