27" to 700 is usually ok without having to change the brakes and don't look out of place. If you want to keep to 27" , second hand alloy rims /wheels do turn up on ebay. I think you can get new 27" rims but not much choice and you'd have to build the wheel.
To be honest for city riding steel rims with salmon kool stop pads is fine as long as you respect the limitations. I swap rims more for weight than braking. however if you/she want to ride fast I would definitely switch to alloy.
