ought to have +should

"You ought to have brought your own 6-pack to the party, shouldn't you?"

Since text-books say that Americans prefer "should" to "ought to" in negative sentences and in questions, can I use them in one sentence?

It's not at all natural like that. Use one or the other, don't mix them.

I can't say that this would be wrong, but I certainly agree with bhai's comment in post 2; don't mix them. While the link you've posted finds this acceptable, I wouldn't mix them, though many AmE-speakers do. I find "ought not we" awkward , but as bhai says, "oughtn't we" is perfectly natural. As for AmE usage, you will surely hear "should" more often than "ought to."
