First off, welcome to the forum!
As for your question, I too would just remove the old chair rail and start fresh without it. You can always replace that chair rail with a cap rail made from the same 1X4 ripped down to a 1X2...endless possibilities!
But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. James 3:17
