Friend,
I agree with David Price.
I haven't been able to hit with "period-correct" sights for over 2 decades. So when I build a gun for me, to shoot, I build it with sights that I can see well enough to hit with. We need to remember that the average user of original guns was a 16 to 25 year-old kid. I'm old enough to be that kid's grandfather!
The front sight on my go-to hunting rifle is 1/8th inch wide and 1/4th inch tall, made from a silver dollar folded over on itself. It's profile is similar to the period sights but with its back edge filed to 45 degrees to the axis of the bore. The rear sight has a square sided notch that is wide enough that there is as much open space on either side of the front sight as the front sight appears when the rifle is held as if to shoot. This maximizes the clarity of the sights for someone with "experienced" eyes.
I have probably made new, useable sights for a dozen rifles owned by friends and relatives. Each time a rifle that had been relegated to the gun cabinet was returned to active use.
Decide what you are going to use the gun for and make the sights for that use.
Best Regards,
