Is it possible to have a true 100% parallax free sight/scope (regardless of distance)??

1. Mirror#1 to take what the a gunner would see through a view finder
2. Mirror#2 to reflect the image of Mirror#1 back to a gunner eyes
3. Superimpose a red dot on Mirror #2 before reflecting the image back the gunner eyes.

Do you think the above approach would solve the parallax problem regardless of distance?

Here is the conceptual design:

I believe parallax is introduced when you magnify the image. It has to do with focal lengths and whether the reticle (or dot or whatever) is in the focal plane for whatever distance you are looking at.

It looks like in your design, the last mirror (the one that merges the red dot and the target image) would have to be two mirrors. In your design you have two angles coming in (the light and the red dot) and they are going out at one angle. That wouldn't work. Look at the angle the light is hitting the mirror before it hits your eye.
 
You are correct. I have no intention to work out all simple details. Hopefully the diagram illustrates the concept is technically feasible.
