Hi there. I think I know the answer, but I need reassurance.

Some repairing/remodelling I am doing requires that I butt up a new piece of drywall to an existing edge. This existing edge just so happens to be a bull nose. In fact, it is a header over an entrance way we are closing off. So I have a bull nose running floor to a height of 80 inch, and then across 72 inch to the wall.

This is in the basement, and because of low ceiling height, there is only about 6 inch from the horizontal bull nose to the ceiling. Likewise, on the vertical bull nose, there is a door right next to it, so the casing for that door is only about 5 inch away from the vertical bull nose.

Any the question is;

Can I butt up my new drywall to these existing bull noses, and feather it out with mud, or is it going to look like mud

You would need to tape the seam. The final outcome would depend on your taping/mudding skills.
