If you want to engrave a famous seal, the name is two words. Just add a seal to the name when you engrave the seal. The signature is in simplified Chinese. If the name stamp is in traditional Chinese characters or other fonts, you can't stamp it in traditional Chinese characters if the other party requests to stamp it in the same words on your ID card. Because simplified Chinese characters are published in the State Council and are common in Chinese mainland, traditional Chinese characters are not common in Chinese mainland. So I think it's better for you to carve the seal according to the name on your ID card.
