Is a clutch replacement able to be done by the home mechanic, yes.

With that "average skill level" could mean many different things. Is changing oil and bleeding brakes at or near you limit then this is not a DIY project If you are comfortable diggin into a motor or trans then this will not be an issue.

You are describing the two situation at the extreme end of the scale. But it woul dbe interesting to know what the average skilled person can or shouldn't do. " changing oil and bleeding brakes" isn't a big deal to me but I am not "comfortable diggin into a motor or trans". So should I attempt this job or not?

Each person has to know their limits. If you are not comfortable with more complex disassembly/reassessembly then a a BMW dry clutch replacement is probably not something to attempt.
