Are both IRA1 and IRA2 yours?
If so, you could move money from IRA2 to IRA1 to increase the size of the 72(t) as much as possible and minimize the 10% penalty as much as possible. So you might be looking at a $30K 72(t) and a $10K withdrawal instead of $20K/$20K.
Alternatively, if you don't want to move money, you can split IRA2 into IRA2.1 and IRA2.2, and take a second 72(t) from IRA2.1 and your 10% penalized withdrawals from IRA2.2. You can have more than one 72(t) program going at once, and you can in fact use different approved methods for each 72(t) if you want to.
Note that you must take SEPPs for 5 years or until 59.5, whichever is longer. Since your profile says you're 53 now, that would mean until you turn 59.5 if you start any time soon.
