Would a Spot-Hogg or Truglo tritium pin be compatible with the Copper John setup?

I looked at the Copper John sights and they do look pretty robust and well made. I've been using Tritium sights on firearms for years. Having a 20-30 yd. Tritium pin on a SH or CJ sight would certainly solve any low light issues without having to rely on batteries or huge spools of fiber optics.
