Keep in mind we're not talking phantom, we're talking 9v plug-in, which is not the same. I've never heard of a phantom mod and I doubt there would be room in the box. It would be cool, and if someone can prove me wrong I'd love to hear about it.
I don't think that much space is required: a few caps, four 6.8 kOhms phantom drop resistors and the actual 9->48 Volts DC-DC converter of course. A few parts for "support" must in as well if the 48 Volts rail is noisy, RF problems pop up, etc. etc...
Overall it will be a small challenge to find the necessary space for these parts, attach them securely and identify/rectify any problem that that might occur due to these changes.
Also, with the P48 generator on board, the drain on the AD-20 battery will probably double (to 100 mA).
