No.

Even if the idea occurred to anyone, and they tried it, they would 
fail. Because, even if the idea itself hasn't happened yet, we have 
*already experienced* the time to which they would return, and Sirius 
died. The events they want to affect have already happened.

Take Buckbeak--he was never actually killed. They didn't go back and 
*change* things--they were simply a part of the things that did 
occur, that already had happened. If an attempt to save Sirius were 
made, we would already have seen that attempt during the fight scene, 
and if one was made, it clearly didn't work.

So, I'd have to say no, use of the time-turner wouldn't save him, 
because he's already died. If the time-turner were used to save him, 
he would have survived; we just wouldn't know why yet (much like 
Buckbeak).

Sorry.
