To be honest, I wouldn't base Bozak's value based off of a bunch of fed up fans. People were saying that about Franson last year (and same with Lupul, Phaneuf, Kessel, etc.). The thing that was always so confusing is that Bozak never really disappointed, so I don't see the justification behind people wanting to get rid of him for whatever they can. Bozak is worth a whole lot more than Kerdiles one for one, never mind the other pieces involved giving them even more value.
Stoner gives us a Fayne-like anchor contract. Boyes actually has some good value considering he only costs 700k and can do the same amount (or more) as someone like Fleishmann did last year. He had something like a 4.5 million cap hit and picked up a 3rd round pick despite that. Marincin is Marincin, but we can include him as a decent value add on in a bigger package (like this one, but not this one).
If we REALLY like Kerdiles for some reason, I can see Boyes + Marincin for Kerdiles and maybe a mid round pick (or just take picks from them if we don't), but that's about as far as I'd take it.
