I'm a little confused by this suggestion - surely on Wikidata, the natural thing is for Game (Q11410) should have the subclass of Videogame (Q7889), or vice versa, and each of those items should link out to their equivalents of schema.org/Game / schema.org/VideoGame.
I'm not sure why we then need to add that Game has an external subclass of schema.org/VideoGame - surely this is just repeating information we already have? Mirroring all of schema.org, including its internal relationships, directly within Wikidata seems a bit excessive.
Am I missing something really obvious here? Nemo's suggestion to just create a new Wikidata entry (item, topic, Q-number) for any missing concepts, and then use the existing class properties, seems to solve the core problem without introducing excessive complexity...

Andra,
That type of powerful expressiveness is certainly doable in Wikidata. To blatantly create properties on a whim by pseudo proxy of using Wikidata items to do the heavy lifting. But that idea is against most of what I have seen in Wikidata documentation, policy, and community best practices say to do.
The right way forward is to patiently wait for the new property to exist, and then we can continue. Thank you for drafting the property proposal by the way. I'll wait for it for review.
Here's some examples where we have subclasses under these :
https://www.wikidata.org/wiki/Q4026292 Action should also ideally have all of Schema.org's subclasses of Action that we have like http://schema.org/TravelAction
https://www.wikidata.org/wiki/Q11410 Game should also ideally have the subclass of Videogame http://schema.org/VideoGame
Here's an example of flipping it around and saying that Schema.org can be used as an 'external parent class' https://www.wikidata.org/wiki/Q7889 Videogame should also ideally have a proeprty on it for 'external parent class' or something similar with the value of http://schema.org/Game
