Pardon my ignorance in this area but is too much to ask for OTDR data before

wanted to do xWDM in the future.
Yes, it's too much to ask.

In my experience in leasing dark fiber strands over long distance the
providers usually give the option for regen colo space. And in some
cases they wanted to know full specs of the equipment you are going to
be using so there is no questions if it will work or not.

You would need at least one router for this.
Personally I would connect both DSL modems into a small Cisco router or

While not at all touching the accuracy of knujon's stats with a
bargepole, it would be interesting if some process were developed to
deaccredit or otherwise kill off the shell registrars .. and the bogus
LIRs (which is how the thread started).
