No. In order to book your 4th fastpass in a second park on the same day, you have to travel to that park and be physically present in the park before booking an additional fastpass.
You never know what might pop up. People book and cancel fastpasses all the time. On my last trip, I was unable to get a 7 Dwarves fastpass and had resigned myself to not riding during that trip (Standby lines were way too long for my taste) but it popped up as fastpass availability when I was looking for a fourth fastpass. However, I wouldn't count on the big rides popping up (particularly if you have a larger group) and, if they do, the fastpass may be hours away thereby eliminating, or nearly eliminating, your ability to get any more fastpasses for the day.
Thanks for your help!
