Since you don't have a ROPS, you shouldn't have a seat belt either (which is a good thing since you don't have a ROPS).
Using the carryall is a good idea. It may prevent a full back flip, but it's quite likely the tractor would roll to the side then. However, the carryall may slow the rate of roll enough for you to hit the clutch and brakes. The slower you go, the more time you may have. If you want to get an idea of how much time, mark one of your tires so you can see it from the seat. Use the gear and speed you intend you operate at, then time how long it takes to make one revolution of the tire. That would be a good indication of how much time you'd have to react. However, remember that if it's a full revolution, the tractor is all the way over, so account for that...if the tires make a full revolution when it gets hung up, you'd better be off the machine running.
According to the reports and tests I've read, once the front of the tractor is up 75°, it'll continue due to momentum. Also, the back rollover takes about ¾ of a second to reach the point of no return (that 75°).
About all you can do is jump...and hope the machine doesn't side roll (since the carryall will prevent the tractor from going all the way over.
I'd strongly advise you not to skid trunks (or anything else) by yourself. Have someone walking far enough away so they wouldn't be in the danger zone. That person can render aid or call for emergency assistance.
Be carefull...go slow!
