Can I sell Leap Calandar Spreads?

I was watching a tutorial doing covered calls using Leaps, also vertical spreads etc.

My question is: why not buy a current month ITM put, and sell the farthest out ITM Leap put at the same strike price?? (Making the strike price very attractive to be assigned. That would give you huge credit. If you got assigned on the short put, couldn't you just exercise the long put to satisfy the assignment? And keep the credit???

Example: Today Google trading at approx. 482

So: Buy Sep'10 550 Put
Sell Jan'12 550 Put Total Credit is 35.05 approx

When short put is assigned, exercise the long put
If there is no assignment, roll the long put to the next month.

Does this sound reasonable?? I searched all over and the closest I came to this was something called a reverse calandar credit spread. It wasn't explained well but I think it might be what I am talking about.
