Can Forsythia be grafted?

Hello IBC,
I am wondering if anyone has successfully grafted Forsythia before. I have a large Forsythia stump, large leafed variety, and I want to graft dwarf Forsythia scions to it for smaller nodes and better ramification of the tree. Can this be done?
I know I can graft a couple of "trials" to see if they would take... Thank you for your help.

Many of the real dwarf cultivars of Forsythia do not blossom. Make certain the cultivar you select flowers.

Thank you Bill, I didn't know that. The variety I have is a proven prolific bloomer. I don't know the name of this variety but I have been growing it for many years.

I just found an Internet site which sells high grafted Forsythia, so I think I have my answer   

Yah. I think about anything can be grafted.
