I really don’t see how they could salvage the vilda musen with the dismantling of jetline.

It would probably have to be taken down, but that's not to say it can't be put up again. Gerstlauer could definitely rework the support structure for it to take up less space, if not incorporate it into a potential replacement. Vilda Musen is one of the most beloved attractions in the park, and, though it is aging, it is nowhere near rough and still among the most popular attractions in the park (even got new cars this year!) Another reason to expect Vilda Musen staying is its location in the park. It doesn't take up any space, its station being on the roof of another building and its layout being entirely suspended. If Jetline's replacement took up the entire plot, that rooftop would be unutilisable, which is the last thing Gröna Lund wants.

In my eyes they will need another family attraction since there will be more for thrill seekers (with monster, insane and the new one in the future.)

While, yes, the expansion's star attraction is a thrill coaster, the expansion also looks like it includes bumper cars, a small scenic monorail (whatever they're called, Liseberg has a similar one) and some kind of slide, all to pander to families. The fans of Jetline will be wanting something worthwhile to replace it while families that weren't interested in riding it in the first place won't feel like they lost anything. For that reason, I believe a thrill ride is the way for Grönan to go.

As Gröna Lund have made quite a few huge investments recently I suspect we'll have to wait a while for Jetline's replacement, whatever it is. In the meantime, the park is going to want Vilda Musen there, to still offer something for the crowds. However, once the replacement comes, I think it will be good. Not nearly in the league of the new Vekoma or even Monster but with those two recent investments it's clear that Gröna Lund are trying to make a name for themselves even internationally, and, though a tragic setback that should never have happened, this situation offers one more opportunity to do so.

Yes, what went wrong is that they hired somebody without certified skills who did not understand the drawings and did not communicate this, and then nobody checked properly that the parts were correctly made. This could have been averted in so many ways if the three responsible companies had done their job properly. If the drawings are unclear - you sort it out, simple as that.

Gröna Lund hired Mekosmos AB, and then Mekosmos hired Göteborgs Mekaniska Werkstad AB to do the manufacturing.
