Can sbsars works as smart filters in Photoshop?

I did simple height to normal map filter and it looks like working. Then  I did simple blur  filter for rgba input  and it doesn't?   did a simple pixel processor filter that  adds values to RGBA input  and it doesn't work .   

Can you use sbsars to make our own filters for photoshop  or we can't?    and can we make them work in document native resolution?
