Yes, it is. I backup by data that way since Q4 - the qubes-backup may
be more "handy", but I prefer knowing every single detail on encryption,
etc myself. You may mount a luks-container in sys-usb (for example), and
then attach one-by-one your app-vm private.img to sys-usb using the
qubes widget; after mounting them (ro of course) you can simply rsync
your data, most conveniently to the backup volume. Your app-vm will not
be exposed to usb that way.
If you have a full dd take of your qubes system (I understood you inital
mail like that), be aware that the some image files are rather like "dd
disk images" rather than "dd partition images", which means you cannot
use the most straightforward mount on the loop device (you never mount a
disc, but a partition!). Instead, have to read the offset of the
partition start using fdisk or similar, and provide this offset to the
mount command. A quick google reveals the details on this procedure :)

That's a pretty cool and nice trick, I'm definitely gonna play with it when I
get the time for it. I feel the same about such programs too, complex backup
mechanisms are a single point of failure... I might just adapt your habit
there, even though this isn't my thread/issue, I'll still say thanks for
sharing.
Hopefully that solves the OP problem though, it seems like it's exactly what
he's looking for by the looks of it.
There is not much difference between the manual method OP describes and
the way qvm-backup does it (automatically).
If you follow the emergency backup recovery docs, it lays out manual
steps for recovering Qubes data as img files which you can then mount:
