I've been meaning to help you with this but I'd been focused on the new Tomb Raider lately. Now that I'd finally gotten my new HD capture device, I came back to this thread and decided to help you out.
So I've never heard of such a patch and never tried the Aquila technique myself. I went into Training, experimented and tested it all out for you and it seems it's still very much possible. Then I actually took the time to produce a video for you (while testing out my device's 1080p quality) so you can see how it's done.
By the way, the technique you're talking about (which I labeled as Variation 2 in my video) is very difficult to perform since you have to hold Angel Mode, perform Caliber, release Angel Mode, Jump, Melee, Jump, hold Angel Mode, Caliber, etc. I had to use my arcade fightstick just to make it easier for myself, lol. So I'd recommend using Variation 3 since it's a lot more convenient on the hands if you're using a controller. If you have any questions after watching the video feel free to ask.
