Greensleeves - hammered psaltery

I got this great little plucked psaltery . lap harp from Brooks Hill Music in December 2012. I added the reference dots by punching gold foil and gluing those dots in place where I wanted them. Also added the stick-on letters. Wondered if it might be possible to also hammer this like a hammered dulcimer. Bought some student hammers and have been trying those out recently. Recorded 3 songs this evening just for fun. So.... hammered psaltery anyone?
