Best way to do this probably, you would need to merge the output of pixel mad into your lighting console using a DMX (artnet) in and use HTP merge.
This way you can use it as a regular fixture or pixel mad.

There is a magic panel fixture in pixel mad, just patch it where it needs to go, +16 channels from the start of the fixture.

If you can't do that then, just patch the moving light portion of the magic panel on the console and have the console and pixel mad both going through the same switch talk to the magic panel. I don't like this solution as much but it would work.
