Not to Be Encouraged, but
doubleu
I certainly don't encourage this as a SOP, but it can be valuable in an advanced training program. Definitely something I wouldn't try with a student or PPL, but not a bad awareness addition to CPL (assuming they already have an IR) or FI training. Something along the lines of upset recovery training.
The flight planning is intense and the inflight workload is exhausting. 150 NM of this and you'll feel like you've just flown 6 hours of hard IMC by hand. Real world, I'd rather go up, punch holes in the clouds, keep my eyes on the panel, and have those little voices on the radio telling me when and where to turn and when to go up or down.
A good lesson in why you don't want to do this, and also on how to do it safely and what to expect if you're forced into doing it.
