I can only judge the Westminster and Augsburg Confessions according to what they actually say and according to scripture. Your innovative view of baptism does not agree with either confession.

The grace which is exhibited in or by the sacraments rightly used, is not conferred by any power in them; neither does the efficacy of a sacrament depend upon the piety or intention of him that does administer it:[7] but upon the work of the Spirit,[8] and the word of institution, which contains, together with a precept authorizing the use thereof, a promise of benefit to worthy receivers.[9]
Westminster Confession, Of the Sacraments
For proof that the Westminster Confession is correct, I suggest you examine the referenced scripture texts.

[7] ROM 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: 29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God. 1PE 3:21 The like figure whereunto even baptism doth also now save us(not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ.
[8] MAT 3:11 I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire. 1CO 12:13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
[9] MAT 26:27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; 28 For this is my blood of the new testament, which is shed for many for the remission of sins. MAT 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
