Sure you could do it. You'll only have around a net 40% of your 401k balance, however, after all the taxes and penalties are inflicted.
And then what do you do the next time you run into difficulties? Which very well might happen...you never know what life has in store for you.
Go to the Dept. of Justice website to find an approved credit counselor in your area: http://www.justice.gov/ust/eo/bapcpa/ccde/cc_approved.htm
Stop using your credit cards, and get a plan for repayment put into place with the credit counselors. Go on a budget and learn to live on less than you make. That's what retirement's all about - learning to live on less than what you had before. We actually have MORE income retired than we did working, but increasing costs and inflation always hurt. House maintenance, for example, doesn't go away magically just because you aren't getting performance bonuses any longer.
To replace a $140K income if you retired tomorrow, you would need….$3.5 million (4% drawdown). Are you close to that? Doubtful.
Reduce your expenses, pay off expensive revolving credit, and start saving seriously.
