Mixing stained trim with painted

I bought a 1980’s home with stained poplar trim and white oak floors. I’m replacing the carpeted areas with white oak and refinishing the originals to match. I will also be replacing the stair rails, newels and balusters when I refinish the stairs.

I originally planned to keep all trim, but the baseboard are 3 1/4” and the doors are a raised 4 panel in rough shape. The windows and window casing are in good condition. It is possible to harmoniously mix stained windows and window casing with painted baseboards, doors and door casing.
