There are two approaches for that.
One very tacky would be to hardcode some IR into a IR processor - there are some plugins to do that - and publish it as a plugin per se.
The second, which is what we are aiming for, would be a plugin to which you can upload the IR files directly from the GUI. The biggest barrier here is the file handling and management.
This feature is in the roadmap. When we have it not only IRs will be possible, but also sample, loops and etc.
