There may or may not be such a things as "Devuan Stretch" but if there isn't there might be an easy way to convert "Debian Stretch" into a Devuan like distro. See thread:musher0 wrote: I may be wrong, but I think there is no such thing as a "Devuan Stretch".
The DPupStetch-7.0 that I have at augras' repo is based on Debian. The
others are easily recognizable: my xenialPup-7.0.6 is of course based on
Ubuntu packages, and the Puduan-6 is, as you already know, based on
Devuan packages. When I say "are based", I mean that I have built them
with the help of the corresponding Woof-CE scripts.
BFN.
Turn Your DebianDog Into Devuan - a simple howto
However, I don't know if it has been tested for compatibility:
"Do all the existing packages in Debian Dog match what is in Devuan? Don't you risk conflicts if just change the repositories on Debian Dog without replacing everything if an existing package in Debian Dog is different than its equivalent in Devuan?"

Edit: I don't think that it would be hard to write a script to swap the debiandog binaries with the equivalent version from the closest version of DEVUAN. However, then the result would be something closer to a particular version of DEVAUN then a particular version of Debian.
