yes - you may do so - but by reducing your Schedule A deductions - you will have additional tax liabilities because your taxable income will increase.
Also adjusted gross income (AGI) is taken from the line 37 form 1040 - http://www.irs.gov/pub/irs-pdf/f1040.pdf
while itemize deduction amount from schedule A will go to the line 40 - and changing that amount will not affect AGI.
I would expect that after proposed changes your overall tax liability will increase.
Let me know if you need any help with reporting.

Yes you are correct that my taxlibility will go up.(in fact by $900.)
But it seems that if I have to file the 6251 my tax goes up 7K.
By lowering my itemized duductions by using the sales tax tables in leu of actuals
my "taxable income" will be reduced enough to eliminate AMT impact.
Can I lower my deduction after I have submitted. Is this legal and will the IRS allow?I
Yes - you may do so by filing am amended tax return - form 1040X.
But I have a feeling that you made a mistake somewhere in calculating AMT. Please verify.
