No. The rules changed in 2015, you can't claim against a spouse and delay claiming on your own record. When you apply for benefits, you are deemed to be applying for every possible type of benefit you are eligible for, all at the same time.
Your spouse's benefit at full retirement age would be whatever she is entitled to on her own record, or half your benefit, whichever is larger. If your wife retires early, her benefits will be permanently reduced.
