Thanks for all the replies. This happened to a friend of mine recently on a sim assessment. He was asked to intercept the final approach track from 2500 instead of the published 2000. The examiner playing the ATC role didn't give him further descent but cleared him for the approach. He opted for a steeper initial descent from 2500 at the FAF, and after quite a struggle, managed to get on the correct profile and stabilize himself. But indeed, it's much harder work to manage the energy so I too think it's better to extend outwards and upwards. I mean there's no regulation prohibiting you to do this as far as I gather.
