Dedicated Unity service Server and Matchmaking for a turn-based tactical RPG

Hello. I'm developing a tactical RPG like Disgaea or Fire Emblem for PC, with the exception it is online/2 person PvP so it needs a dedicated server to avoid cheating.

Steps of what I am planning to do:

1) Player creates a map with my map editor

2) Player uploads the map to Unity dedicated Server. I think it's it is cheap and comfy.

3) Player's map is showing on MATCHMAKING list as a room for anyone to join and start playing.

I did some research and figured that Unet dedicated server does not support online matchmaking. Or does it? I'm a bit confused.

I need some clarifications:

A) Is the above plan possible?

B) I searched in the store for Matchmaking on a dedicated Server and ended up to "Master Server Kit" asset. Can this be the solution?

C) Are Unity Devs, (if the above plan is not possible) working on that direction, somehow for future releases?

D) If I rent Unity dedicated Server Service bandwidth (which I really wish this to happen cause for a turn-based game is quite cheap) what are my publishing options? Can I distribute it through STEAM?

The peer2peer (server host AND client by one of the two players) is a NO GO!

Thank you in advance.
