72(t) SEPP and 401(k) contribution AT THE SAME TIME?

[Sam]

Situation:
Single, female, 44, currently UNemployed by choice. 300K in 401(k).

Plan:
1) Roll 401(k) into Vanguard or Fidelity IRA. Start 72(t) withdrawal, single life, fixed amortization, ~18K/year at today's rate. Continue withdrawal until 59.5.
2) Go back to work a year or two from now. Participate in employer's 401(k) program.

Question:
Can it be done? Is it legal?

Thanks

Sure she can, but why? And as you know, she has to continue her withdrawals until she is 59.5.

Thanks Martha.

She wants to take a long break from work to travel, and possibly to get an advanced degree. Her non-tax deferred saving alone (~40K) is not enough for 2 to 4 years of expenses.
