Inlay trouble

Hi all. A friend of mine as a Peavey Cirrus of some sort and he had custom inlaid dragons put in (don't know why...the look kinda rediculus...hehe). Anyway, the inlays are breaking apart and falling out (might because of the temp. different between California and Nebraska). I was curious as to what we could do to either fix the inlays or to replace them with something else. Your ideas would be much appreciated...thanks.

PS The inlays are on a Koa top and are only about 1.5" wide.
