I would strongly advise against it. Back when I was working in the plastic surgery industry in Korea I would always come across an asian patient who wanted to look caucasian. And the thing is, plastic surgery is about enhancing the original structure of your face/body. When you aim to undergo radical changes, it causes the person to look very fake and unnatural. There were many girls that would come in asking for a caucasian nose for example and to do that on an asian person, who typically has a flatter bridge, wider alars more bulbous tissue in the tip and thicker skin density when compared to caucasians, much structural damage will be sustained follow the procedure which can risk contracture etc. Additionally, the nose tends to look off balance with the asian features. You also gotta remember that asians facial bones have less depth than caucasians. This depth cannot be modified in full but rather all you can do is augment certain parts of your face. However, when augmenting the outer structures of an asian person, the face ends up looking wider and unpleasing. So you gotta consider all that.
