I intended the "Calvin tackled while opening the front door" thing to be explained by the fact that people can touch, and otherwise interact with, their own daemons; in this case, it would be the daemon "interacting with" him.
As to the others - very likely this would need to be at least mildly AU for Calvin and Hobbes, on top of the significant change on the HDM side; I certainly don't think we need to assume that everything depicted in the strip happened verbatim, or even necessarily at all.
I've considered the possibility of there not actually being a physical stuffed-animal Hobbes involved, or if there is, either it only served as the inspiration for what form Hobbes would take or it's used as a type of camouflage so that people who don't know about daemons can at least think they know what Calvin is talking about when he mentions Hobbes.
I don't remember Suzy and Hobbes having conversations at all...
