Basically, --dry-run just simulates unpacking, and dpkg does not check
dependencies (other than Pre-Depends) during that phase. There have
been complaints about that forever, so don't expect it to be fixed

Not with dpkg, but apt can install local .deb files and resolve
dependencies, although this is not documented.
$ apt -s install ./*.deb
should give you information whether the local packages are installable.
Note the leading "./" here, it tells apt to treat the arguments as local
files rather than package names.
