Is the chair rail the same height as the tread top, or bottom of rail same as bottom of molding under tread? Could you live with a different profile on that rail? A narrower rail and/or lowered a bit? Or raised? is there a match in profile of the bottom of rail and tread mold? Make a new rail from tread mold and top part of rail? A new one with same profile as tread and mold?
Remove the short piece of tread mold and angled skirt trim, mebbee mark it across where it meets rail top and bottom first. Extend the rail, cut and replace the skirt trim. If you could get the top of the rail to match and be flush with top of tread and the bottom the same as tread mold it might look OK. Cept for that abrupt change from black to white. Now all you gotta do is replace all the other rails in the room to match the new profile.
Trim the back of that bottom tread even with the riser, extend the rail and return miter rail so bull is flush with riser, new tread mold coped to fit rail. Extend the rail to back of tread, return miter and cope new tread mold to fit and notch return to fit each other. That's complicated to explain ( and do) Thicker molding should return onto thinner, thinner parts cope onto thicker, looks like rail and tread mold will each have a return and a cope.
Orrrr... If enuff vertical height on angle; New rail notched and whittled to fit over new angled trim. Rail just long enough so 90 degree return miter's "nose" doesnt jut past angle. Or notch and cope the angle to accept longer return mitered rail.
Orrrr... Cut out section of angle, extend return mitered rail through gap so bottom meets top of angle.
Ya know, I gotta stop thinkin out loud this way.
