You should go for it. She's your wife, the mother of your kids. That's never gonna change. To me the tattoos mark parts of my life. God forbid anything happens, but even if it does, she's still going to be the mother of your children. And whether you have her image on your body or not, she's still going to be part of your life and your kids' until you die. Any woman you might be with afterwards would have to know and accept that.
Think of it like renewing your vows
