Anyone turned a barrel for a Bic Cristal?

Back in my Jr. High woodshop days, our shop teacher ingeniously came up with a way for us to turn pens without spending a bunch of money on kits. He took a regular old MT2 mandrel, cut it off until the rod was about 5" long and had no threads at the end, and had us drill blind 1/4" holes into pen blanks. The blanks fit right over the mandrel, and with tailstock support, we could make "kitless" pen bodies, and then stick a regular old Bic Round Stic refills into the hole for a nice friction fit. I made a lot of pens like that before I learned about the wide world of kits.

I have a friend whose absolute favorite refill is the 1.6mm Bic Cristal. I wonder if anyone has turned a pen for the venerable Cristal refill using a similar (or any other) technique? If not I may give it a shot and report back.

I made a couple at a workshop with Kurt Hertzog. His technique for getting the refill to stay in the barrel was rather clever - drill it out so it's a snug slip fit, then dampen the inside. With a toothpick, apply the tiniest dot of polyurethane glue (like the original Gorilla Glue) to the inside of the hole and put the refill in place right away. The glue foams. When it is set, give a quick twist to the refill (might need section pliers) and you've created a ridge that holds the refill in place but with a firm tug it will come out and you can replace it.
 
Here's some I did. I wanted to replicate the original design. You could shape it in any form you would like.

 
Played with the concept.

Seems straightforward enough. I should clarify that the Bic Round Stic and Bic Cristal have similar but different sized refills. The Cristal will need a hole significantly narrower than the 1/4" that worked great for the Round Stic. Might be a bit of a challenge to find a drill bit narrow enough and long enough at the same time. Then again, maybe I can just drill a normal 7mm hole through most of the blank, and just the end gets a smaller hole. I'll figure something out and report back when I've given it a shot.
