No, you cannot be baptized twice. The sacrament is unique and irremovable, and there is therefore no need for a second baptism. According to the Code of Canon Law only unbaptized individuals are eligible for baptism:
Can. 864 Every unbaptised person, and only such a person, can be baptised.
The Catechism of the Catholic Church also quotes this canon directly:
1246 "Every person not yet baptized and only such a person is able to be baptized."46
If it is uncertain whether someone was baptized the Church may perform what is called a "conditional baptism," but this is very different from a second baptism such as you desire.
