I've figured out the answer and will post it (BTW turns out this is a typical forum)
We withdraw $22000 from our 401ks, which counts as income (don't think I will pay a penalty but even if I do it is a savings).
...
It doesn't really matter if I spend the money withdraw from the 401k instead of using cash savings or put it into Roth IRA far as this topic is concerned.
Thanks to those who helped in the question!!!
Just to add my weight to the Roth conversion side:
As far as getting the subsidy, a 401k withdrawal or a 401k to Roth IRA conversion will both generate income.
You pay the same tax either way also.
However, with a simple 401k withdrawal you may pay a significant penalty (if you don't qualify for the rule of 55). The Roth conversion can be performed at any age without a penalty. Plus a simple 401k withdrawal removes value from your tax-privileged 401k account and moves it into your taxable account. A Roth conversion keeps your money in a tax-privileged account.
Reducing the value of your 401k now may help your tax situation when you turn 70 and have to start RMD's, as pb4uski has pointed out.
