In case anyone else wants to try using a 16 tooth front sprocket and the front sprocket cover, here's my experience.

I first ran them together after grinding away some aluminum from the inside of the sprocket cover to give the chain more clearance on the larger sprocket. I then removed the cover and found that the chain had rubbed against and eaten into the sprocket cover at the front and especially at the bottom, between 7mm and 21mm from the edge facing the transmission. I ground more aluminum away, so that a straight edge over these areas left a 2mm gap. After riding another 300 miles, the chain is no longer contacting or marring the sprocket cover. I'll inspect the inside of the sprocket cover again when I adjust or replace the chain.
