(Dream) Wei. You can add a cute word in the middle, so it won't sound homophonic. At the same time, you can keep the good name "Wei" and add your mother's surname. If you think this "Meng" is not satisfactory, you can use this word "dream".
If you are not satisfied, you can change it to "Meng", which is more suitable for men.
I hope you are satisfied. Thank you.
