Now, there's certainly a logic in economies of scale, getting the stadium used more than one day a week for one team. The problem in that respect has been that Wasps have been set up as primary user, whereas it needs to be flipped really. Isn't easy, and of course the teams have had difficulties, but Swansea, Hull, Huddersfield etc manage to run a Rugby team in the ground alongside the football team.
Another problem of course is Wasps are interlopers, and do you want to attach them to CCFC? A potential owner with balls / lack of empathy might well override that though, do some serious re-branding with Wasps to make them a Sky Blue Rugby team. Running Wasps as the extra could be a (relatively!) cheap way of getting more footfall / awareness for the arena and also indirectly for the football club. If they were secondary to the concerns of the football club you could reign in their sit or bust approach too, while also offering ticket bundles and offers across clubs to try and cross-pollinate.
Now... personally I don't want us near Wasps, I'd rather they withered and died. The above is also not without risk of course but... what isn't. It is however what a potential owner might consider, as ultimately the Wasps team part is a small add-on in comparison to the rest. If you then brought Cov Utd ladies back under the CCFC banner, you can start to do what Wasps made aspirations of doing, but maybe properly. As it's us of course, it'd all drag the football team down to oblivion as the rest fell!
