No, don't try to mix it up. I would keep all the door hardware the same as far as the interior doors to each room goes. The kitchen cabinetry, bathroom vanity and faucets can be shiny chrome, antique bronze or or brushed nickle...whatever you like, but your interior doors and hinges should all match. I did this with our new house and have Swarovski crystal knobs on our ensuite vanity with a chrome faucet set and brushed nickle fixtures in another bath, but my kitchen cabinetry knobs, front door entry and interior doors are all unified by having black matte colour metal lever hardware. In your case I would carry the bronze hardware all the way through in your interior door hardware and hinges. No one will notice the change. Good luck with your new house! :)
