Kind of curiosity, but let's mention it.
Have you heard of any planned connections to feed into Ryanair flights? Yes, sure, it can be true with buses, but do you know of any flights?
Åland Islands is a Swedish-speaking region of Finland on the Baltic sea. As announced, the small local Air Åland is going to start flights from Mariehamn to Turku and, as their CEO says, they count on passengers changing there into FR flights to London.
A good initiative, even it's hardly the official cooperation. So far Ryanair do not want to cooperate with anybody in such questions, being reluctant to provide any connections even within their own network. A pity, I'd say.
