I have a harmony 650 and flirc setup with my sheild and it works perfect, every command you need for kodi or the sheild menu can be set up easily. In my harmony add sheild and flirc as a device, map all flirc commands you want to use to flirc via the flirc software then add an activity and add the commands you want to use from both.
The only sheild commands I use are the directional buttons and the exit button. All other commands from flirc.

The Shield won't receive those commands, well, it won't understand them, so no you can't do it that way with IR.

Thanks for the answers, I now just have to find the time.
