Hey, I like it! I have a box of 1/2" corian banks that I got from Ebay, thinking I could get a slimline from them. I was wrong by about 1/16 of an inch! They're all mismatched, so I didn't think to glue them up... But I've gotta say, this has convinced me otherwise!
You should consider cutting one of your glued up blanks into slices, and then slightly rotating each slice to get a stair step pattern. I first read about that trick in Barry Gross' Pen Turner's Workbook, which is well worth a look. There's an example of the kind of pen I'm talking about on the cover.
