It is hard to give an opinion without knowing what style of kitchen that you have. Stainless steel hoods can be gorgeous and very sleek looking.

You might want to look into having a custom hood built built by a carpenter that could be finished with a skip troweled stucco finish. You could then use the same tile that you have on your backsplash as a band around the bottom of the hood. Make the hood with swooped sides and front for a French country style kitchen.

Consider getting a hood enclosure from the cabinet manufacture that matches your cabinets. Use decorative brackets or corbels underneath for added style.

Consider having an interior designer come with some sketches for a custom enclosure.

The above ideas will require a hood insert instead of a stainless unit that has the blower built in. Check local codes as they relate to what is required to ventilate a 48" rang. Some city's require a separate heating and cooling system when the blower is 600 cfm or greater.
