If I added the kaiju sub-type to a bone devil with class levels, how much would you change the CR?

More an advice question than a Rule question.
Kaiju isn't a template, so I would compare it to a normal version of the creature and try to evaluate its CR using the monster creation and monster advancement rules.
To me the Colossal size seems a requirement, so a large bone devil kaiju seems inappropriate. I think you would have to increase its size too.
Good point. I'll post in the advice forum
Specifically adding giant template multiple times until it's Colossal+ (once over colossal) would put it to CR+4, but the monster would be a bit of a mangled mess of AC, Dex, and attack with practically no HP to match.
About what difficulty would you even want the fight?

DR 30 epic and fast healing 30 covers the HP problem (unless the party has easy access to epic weapons), BAB can be a problem, depending on the creature class levels.
It all depends on the goal. A gigantic Bone devil that is almost untouchable by physical attacks, and (arguably) magic, that can easily level buildings but has a mediocre attack against medium-sized creatures can be an interesting challenge if the party needs to discover its weakness to overcome it.
