This tar option might be what you're looking for:

 --no-overwrite-dir
       preserve metadata of existing directories

I tested as follows:

$ mkdir a b a/diffowner
$ sudo mkdir b/diffowner
$ sudo chmod a+w b/diffowner
$ echo foo > a/diffowner/foo
$ tar -C a -cvf test.tar diffowner
diffowner/
diffowner/foo
$ tar -C b --no-overwrite-dir -xvf test.tar diffowner
diffowner/
diffowner/foo
$ echo $?
0
