Of course we all see the injury issue. But have to remember its also the only reason he's available and why his contract isn't outlandish. For a small market team, this is a risk you have to consider. Lots of players who are injury prone have it go away and stay healthy, and lots stay being injury prone. A team like MKE can't buy players at market cost without flaws but one like this they can and then cross your fingers you can get lucky.
Financially, yes there will likely be one overlap year with Hoskins (I assume as of now that he'll pick up his option and be back) next year but after that you're essentially just moving Hoskins money over to him. Before this year we've spending the 8-10 mil on the Mccutcheon/Winker veteran types, well this guy is only like 8 mil more than that.
So it really comes down to prospect costs imo. And yea if he still commands a ridiculous haul then pass on him and carry on as is. But, with the issues mentioned and that in general nobody gives up top top shelf prospects anymore my guess is it wouldn't be absurd. Especially since we'd almost assuredly be giving up a ML ready OF Frelick/Mitchell type so that's a solid starting block. I guess I'd also note I'm much more skeptical on our young OFs than most and don't see the harm in a cash out while you can type strategy on them.
ETA: I guess if you do get lucky and he can stay healthier keep in mind you'll be able to trade him for a larger package before his FA season as well. Could apply the 'cash out' idea to him as well if you can get a healthy 2025 or 26 out of him
