Multi-arch Netinstall CD ISO of ASCII 2.1 ?

Visited Devuan ASCII's installer-iso downloads webpage <devuan
mirror>/devuan/ascii/installer-iso/ and notice that there are entirely
separate CD images for the amd64 and i386 netinstall ISO's. Native
systemd-encumbered Debian GNU/Linux Stable "Buster" already _has_ a
multi-arch amd64-i386 netinst ISO of ~615M available for download at
https://cdimage.debian.org/debian-cd/current/multi-arch/iso-cd/

Any way of finding a similar multi-arch netinst ISO CD for Devuan? Or else
an _easy_ way of creating such a multi-arch netinst ISO CD from both amd64
and i386 netinst images at <devuan mirror>/devuan/ascii/installer-iso/ ??
Because the required use-case scenario for such a Devuan multi-arch
netinst ISO is for _native_ installs (and as "Rescue"-type
troubleshooting) on _both_ amd64 machines +and+ on the several i386
machines that are still around.

Upon doing an online search using the search terms "Devuan" and
"multi-arch", the two major resulting hits were of Debian GNU/Linux's more
complex https://wiki.debian.org/Multiarch/HOWTO and
https://wiki.debian.org/Multiarch

Any _productive_ ideas on this Devuan multi-arch ISO CD goal from Rick M
(Knowledgebase at http://linuxmafia.com/kb/ ), from Steve L (Linux Library
at http://troubleshooters.com/linux/ ), or from others reading this??
