The answer used to be no, I suppose. I think Dyne planned to add 35 days for each route and an epilogue. But now in Twitter and Telegram we see the announcement of a special episode with Spencer and Azaghal. In my opinion, the chance of extra days/special episodes/alternative stories was 0.01% and now its 99.99%. But I suppose it can be an extra extra content and will be only available for the patreon supporters. Like you, I also want more content with Papa Bear. It will always be not enough of him for me.
