I think for me the OutputHandler is indeed the combination of your 
LogHandler and a formatter, with the difference that Transcript, file, 
etc. for me are all realized with the same kind of LogHandler; possibly 
created with different class methods.

The problem with this is that in some cases the LogHandler might need 
the severity and category, as is the case for syslog (and I expect 
special handling of date/time in some cases might be desirable, for 
example to put a limit on the number of messages per second).

It could be done entirely with a MultiplexOutputHandler that also takes 
care about filtering unwanted severities, yes.
