Azi, I hear you, but at this point re shidduchim, it’s too late. People know your family, and a superficial change, or a change made superficially, is meaningless. Hopefully people know your mother as a baalas chesed, a baalas middos, who raised a fine young man like you.
Also, as important as this is to you, to the point that you wonder if you should throw out your mother’s property, how consistent are you? This is a level of frumkeit but it is almost superficial. There is shemiras halashon, kashrus, so many things. Do you measure up perfectly yourself? You’re not in shidduchim yet, are you? Because part of growing up for most people is starting to cut others slack and losing some sanctimonious. You may need more time.
