You should be able to. It's similar to adding the Pickit3, but instead of using PK3CMD.EXE you'll need to use the file from the MPLABX folder mplab_ipe\icd3cmd.exe

See this thread for adding a custom programmer http://www.picbasic.co.uk/forum/showthread.php?t=14064.
I'm sure there are other posts, as well as the MCSX IDE help.

The command-line options for icd3cmd.exe can be found in the MPLABX folder docs\Readme for RealICECMD_ICD3CMD.htm

Give it a try and see how it goes.
