Doors – Filling a gap in double-active free-swing double-doors

doors

I have a set of double doors into a water closet (within a larger bathroom) which we want to keep as free swinging with each door being able to swing past each other.

The upper hinge is mounted into the door frame, so it's not really possible to offset the doors from the jamb to reduce the center gap.

A (very large) astragal would close the gap, but then would let the doors get into an aesthetically unpleasing state depending on which one returned to center first.

Is the best I can achieve here something like 3/4" weather stripping adhered to each door? Or is there something like an astragal, but soft, so it occupies the space without providing a rigid barrier?

"move the doors" and "buy wider doors" are both considered out of scope.

The total gap is currently 1 7/8". Getting it under 1/4" seems like it would be much more aesthetically pleasing.

You could use two soft astragals and make them overlap slightly.

If the sweep (soft part) is very thin, the misalignment of the closed doors will be almost unnoticeable.1 You'll have to shop around to see what you can get. A wider sweep is better because it will flex more. I think the "T" style is more attractive than the draft-stop style. You might have to add some wooden strips to the door edges to narrow the gap slightly.

Here in cross section are some suggested arrangements:
