Are the wires in place? Do you have easy access to power at the chime locations? Do you need a 100% no wire install or could you run wires in a crawl space or attic part of the way? Depending on your comfort zone, you could rework some inexpensive wireless doorbells to interface with wires run in the attic or crawl space.

Could you work with RING?

Another scheme could use Zigbee buttons or radio control buttons that might be used for popup cabinets, projectors, fireplaces, and such to avoid all or most of the wire.

Use whatever technologies you are comfortable with.

As others have suggested, take care to account for current draw and voltage drop in long wire runs.
