Is my plan feasible, leveraging low income situation.

Heres my tax situation in 2020. Total estimated earned income is $3000 between me & non-working wife. Have two kids under 16. 

Is following scenario possible? Could you help if I missed anything ?

My Plan:
$3000 - Earned income

$29,250 - Rollover from husband Trad IRA to Roth IRA

$29,250 - Rollover from wife Trad IRA to Roth IRA

-------------------------------------------------

$61,500 = Total income

My Taxes:

Total Income$61,500
Total Deductions$24,800
Total Exemptions$0
Taxable Income$36,700
Regular Taxes$4,009
Child Tax Credits$4,000
Total Tax with Credits$9
Marginal Tax Rate12%
Tax Amount Owe$9

 

I also read that lower-income taxpayers may be eligible for the "saver's credit" if they contribute to an IRA.

Is tis possible? Could you help if I missed anything ?
