Maybe your drive is too big (more than 8 GB if geometry
is perfect) or has confused geometry (USB does not have
any real CHS geometry, so mismatches between different
components about what CHS should be are frequent) which
made FAT16 CHS a problem? Try using type e (FAT16 LBA)
and maybe compare if type b (FAT32 CHS) fails as type 6
(FAT16 CHS) if you want to do some more experiments :-)

I think FORMAT /Q /U or format without options are nice.

That would be relatively easy with a FAT partitioned image
but gives you side effects: If the image is for size X and
your stick has more space, the rest just stays unused. But
then on the other hand, more fancy approaches like Bernd's
image with ISO and FAT partitions combined have other side
effects, in his case making Windows think that the stick is
so weird that Windows wants to format it :-p

I think because everybody has sticks around and prices are
low, we could try to make people happy with a small image
(whatever is appropriate, maybe 1 GB? Then you also have a
lot of space to add your own data) with fixed partitioning.

Advanced users can use e.g. GPARTED to grow the partition
to fill the stick or can add more partitions, while others
can just re-format the stick when they are done with using
it for DOS. I assume re-formatting is easy in Windows??
