I like the backpack but not so much the partner ghost

Maybe add a separate style for the backpack that makes it more reminiscent of the regular toolbox? That would let it make more sense as a standalone item, and give it more loadout variety outside of halloween

They can't be combined because each one individually is pretty close to the polygon limit for cosmetics.

This would be awesome as just one cosmetic, but I think the fact it's separated ruins it a bit. Not sure if it's a problem with the regions that you separated them for, but either way these really just do not hold up when one is used without the other. The coffin is a pretty basic backpack cosmetic and doesn't make sense at all without the sentry, it really just looks incredibly odd used by itself. The sentry is also really just a pet cosmetic.
