Some pressure treatments for wood are paintable. FWIW, my basement
stairs still look fine after a decade in typical old basement/crawl
space conditions. However,the coarse grained wet treated kind of wood
seems to be a different sort as I found out by attempting to paint an
outdoor rose arbor. There may be primers and paints that are rugged
enough for what you need, perhaps an epoxy paint. Ask at a pro paint
store for best advice.
Your reservations about mix and match materials is valid. Even if it
worked it might not be esthetically pleasing. You might want to
consider some of the prefab assemblies at the box stores for a
complete relacement. Good luck.
