Simply, "Sister-in-law" English does not express seniority in relationships, such as an elder uncle, or a younger cousin, except when expressed with a separate adjective, like "elder". Otherwise, "elder brother's wife" is the most simple way to directly express that concept.

In the English language there is no difference between the wife of an elder brother and the wife of a younger brother or of a twin brother. The wife of any brother is your sister-in-law. If you are actually talking to her, however you should just call her by her name. Nicknames are fine too.
