OJS backend with Wikimedia frontend

I am helping a project looking to implement journal hosting using MediaWiki as a front end:

To what extent could OJS be applicable as a back-end for handling peer review coordination and how well it might be possible to integrate with the front-end mediawiki software where articles would be drafted and peer reviews posted?

You can see some examples of the current front-ends here:

In both cases, the back end relies heavily on inter-editor emails and manual tracking, which is far from ideal. It’d be good to know whether an OJS-based solution is possible before implementing a fully mediawiki back end.
