Adobe DRM worked by downloading an ACSM file that acted as a loader; you opened the ACSM and it validated your ownership of that book and then downloaded the actual book, but if Kobo enables a "download" option they would have to download the actual book. Apparently Kobo has some concern about preserving copy protection if they download the book file with just their in-house DRM.
So I was wondering if it's possible for Calibre to convert a kePub book to a ePub book the way it converted a Sony copy of Harry Potter to a Kindle version? Apparently the Tor books don't have DRM so if Calibre can convert to an earlier version of ePub, then would it work to solve the problem?

You can strip the DRM off of Kobo kepub. But then you are left with a mess. You then use Modify ePub to remove the kepub internals. But again, it's not the same as the real ePub. I've not yet checked to see if the resulting ePub looks OK in ADE.
