They do make brass rivets... That would allow you to have a large enough head to engrave, with a smaller shank.
We never use brass rivets at work, but they do exist... Not sure if it would be worth it to buy them. Rivets are generally dirt cheap, but the price goes up a lot for small quantities... We usually order them by the pound...
(The size rivets I use for picks, theres gotta be a few thousand of them in a pound... So the per rivet cost is almost nothing - when you buy in bulk.)
For a 1/4" wide pick shaft, I would drill a hole no larger than 1/8", preferably 3/32" in it, personally...
