If the only issue is a trade off between a significantly nicer kitchen vs loosing direct access to the garage I would look carefully for alternatives but most likely vote for a better kitchen.
A kitchen is often one of the most important things to home buyers. Many will remodel your brand new kitchen anyway however. If you keep your house longer than 6 years the odds will increase that a buyer will want to remodel the kitchen themselves.
If you close off or change the door be certain the change meets fire resistance requirements.
