Semicolon usage for question-statement combos

I have read the various postings here about how and how not to use semicolons, but I've not seen and answer anything about how to deal with end of the sentence punctuation with sentence-statement combination. Here's my current example.

Did you send the revised report; I have not seen it.

I believe this is a correct usage of a semicolon, but I'm wondering whether there should be a question mark at the end.

I suppose I could reword to I have not seen the revised report; did you send it?, but that just sidesteps the question.

My two answers would be:

1) Did you send the revised report? I have not seen it.

2) Have you sent the revised report? I have not seen it. (I would keep the same tense for both the sentences) (*)

(*) way preferred imo :-)
