If you build custom images you can include the host keys in an overlay image.
Basically using the OpenWrt-ImageBuilder:
make image \
PROFILE="${PROFILE}" \
PACKAGES="${PACKAGES}" \
USER_FILES="_files_wndr3800_"
$ find _files_wndr3800_
_files_wndr3800_/etc/dropbear
_files_wndr3800_/etc/dropbear/dropbear_dss_host_key
_files_wndr3800_/etc/dropbear/dropbear_rsa_host_key
_files_wndr3800_/etc/dropbear/authorized_keys
