Either way, it will be an adventure!

I know it's a minority opinion and you don't seem to care for votes, but I say IF you enjoy working on cars and have a healthy curiosity about Boxsters go ahead.
As you have said, if the engine fails, you have lost under $1k and gained some significant experience. Having replaced an engine and IMS bearing, I know that doing it a second time will go a lot smoother and faster.
Your engine IS compromised and short of spending much more than it is worth, it can not be 'saved'. The failed 2.7 that I pulled apart was full of debris, most of it was aluminum which will not stick to a magnet. Much of the fine debris was adhering to plastic parts and was still very difficult to remove completely in a parts washing tank with a brush.
Worst case: Soon after you reinstall the engine it will catastrophically fail and the car will need to be towed. I wouldn't plan on taking it for any cross country trips.
Best case: Your engine makes it another 5k-10K miles before the wear from damage and tiny particles finally finish it off. At 2k miles a year, that could be 5 years.
Edit: If you do it,
drive it hard and enjoy it; push it to its eventual demise. No sense in taking the trouble if you are going to worry and fear every time you take it out.
