I believe I could. Or a 6809, or a 6800, or an HC11. I even have an original 8008 I never got around to using.
The parts tubes with the Motorola logo are from long ago. Back in the day, Motorola sold the blue parts tube racks to their two-way service shops. The offered packages with a rack which came filled with parts or hardware in the tubes. When you used up the contents of a tube, you re-ordered and got a new tube. You could also buy empties. Later, the tubes they supplied changed and the caps have no logo. Sometimes these show up on ebay.
Here is another more inclusive view of my parts and component storage.
