Yes, its just a Heinie style 1911 front sight dovetail so any 1911 sight of the correct height can work on the gun. If you have someone put a dovetail in your slide tell them to be very careful near the center of the slide when cutting across. FWIW, in my gun, however CZ fixed the "bushing" into the slide created a very hard spot in the middle that the dovetail cutter would not go through very well; I broke two dovetail cutters getting that in there (I think one of them might have even been carbide IIRC) and had to finish the dovetail by hand with a diamond file.
I talked yo you when you first did this project over on CZFORUM and you said you were working with APEXTACTICAL to possibly market the rear sight. I was wondering if anything ever came of that. I have a 84 pre-b that I would love to have better sights on.
