Don't know until you give it a go.
But the pad to keys patch will not work as you will use a different lirc driver (You will have to select the imon pad 2.4g from the lirc setup menu instead of the imon pad/vfd) - you will probably have limited real functionality because of this (unless you assign other keys to up, down left right in the lircd.conf)
As for the setup in LMCE admin, again, you can only try. I presume that because the imon pad 2.4g is part of LIRC then it should work. You will need a different lircd.conf though to copy into the admin device data. You will find it in /etc/lircd.conf when you compile lirc in KDE.
