There's a lot of overlap in that.

A state is a set of (pre) conditions.  A guard is just a small
elaboration of a precondition.  All that's left is the event
(trigger).  Are you saying that the mention of events in such
a model adds an unacceptable complexity?  I wouldn't think so.

I think the "state machine" is closer to what you are proposing
than it is to the procedural alternative.
