Did you end up engraving it? I'd be really interested in seeing it if/when you do.
oh yea, I did a while back forgot to upload a pic. here it is. my laser is very low wattage so its more of marking it vs engraving/cutting into the silver. Apologize for the delay in posting.

I think you did a great job. Uses the available space perfectly but doesn't overload the whole thing or draw too much attention. And also is a well thought out showcase for Bitcoins current lifespan.
Also love the graded ones, they do look really well in a slab. If I weren't in the process of *reducing* my collection I would definitely get one.
