USIfAC drive activity LED and Drive sounds. Possible??

[Mamejay]

Recently got my first CPC464 and a USIfAC.  I love tinkering with hardware was wondering if it would be possible to mod the USIfAC to have a little Piezo speaker and also activity LED.
I come from a Commodore background and similar products I have used were able to be modded to have these features.
Any thoughts on this?

It doesn't really emulate a drive in that way. When you use it in floppy emulator mode, by loading a disk image and then |FDC, it will flash the normal disk access light, even if the drive is not powered!
