libarchive can probably do this kind of thing. Some coding required
however ...
By far the easiest way would be to accept that you need to unpack it
to disk.

Try this...
mkdir dir2
add it to archive via built-in archive software, in my case archive manager for gnome. You should have both dir1 and dir2 in archive. Right click dir1 and chose cut. Navigate into dir2 and paste.
I created directory "test1" and then:
touch test1/file1
touch test1/file2
creating two files in test1. In the file manager I chose to "create archive" then did the above successfully thus restructuring the archive without extraction. Mileage may vary. HTH.
