The minimum shell you should be able to prevent by setting
BUSYBOX=n
in /etc/initramfs-tools/initramfs.conf
Then recreate the initrd e.g. with 'update-initramfs -k all -u'.
dd 'panic=30' or similar to the kernel command line to get it to reboot
on kernel panic after 30 seconds.
However, I doubt this will boot the fallback entry as the initial kernel
+ initrd actually boots as seen by grub. It only fails afterwards. Test
it and tell us if it works as hoped for.
If it doesn't work, it might be possible using grub2 and its scripting
to enable booting the system from usb as soon as it detects a usb drive.
