A Photomorphis BlendKit® will not work with ON1 products.
The BlendKits work because of specific tools (Smart Objects, Smart Filters, etc) used in the BlendKit that are unique to Adobe Photoshop and not available in any other program (including Elements and ON1).
You can learn more about BlendKits in the Photomorphis BlendKit Store.
At the bottom of each Photomorphis BlendKit description you will find the software requirements, including the version number, listed for your convenience.
