Yes, I do similar at the moment.

I just boot the windows guest session and use eraser or winhex to erase free space and then 
recompress with qemu-img.

For ext2/3 I use a kernel and utility initramfs I knocked up and then run zerofree on the partition. 
That works nicely.

I'll investigate ntfswipe as that sounds like it might help me make a fully automated re-compression 
utility.
