No, it wouldn't help much as she is entitled to spousal benefits on your earnings record. Spousal benefits are equal to 50% of your PIA benefit when she attains age 66. For example, if your benefit is $2,500 a month, then she would be entitled to $1,250 at age 66. She could also begin collecting prior to age 66 if you begin collecting benefits or file and suspend your own benefits. A spouse receives the higher of spousal benefits or her benefit (assuming enough quarters of coverage). So if she acquires another 8 quarters of coverage it is very unlikely that this would increase her benefit more than $1,250.
Do to a recent change in the law, if you want to file and suspend, you must do it by April 29th of this year.
