Extending convert would be good if you want to create a new image.
This syntax might be better (no new parameter, final size instead of delta):

qemu-img convert -f qcow2 -O qcow2 -o size=10G original5G.qcow2
output10G.qcow2

For resizing an existing image, a new command is needed:

qemu-img resize -f qcow2 -o size=10G original5G.qcow2

Although there is no urgent need for either variant...
