Impossible
Scholars generally claim Diokles lived in the city of Pherai (Kalamata), which, of course, fits a trip starting from the wrong palace perfectly.
There's one problem, however, because between Kalamata and Sparta lies a huge mountain called Taygetos, which was impossible to cross by horse and carriage in those days.
They put this down to artistic licence on the part of the poet, but it makes no sense to me that Homer, who knows his geography and so far has been quite meticulous about it, would suddenly start using artistic licence.
Telemachos' route starting from our Pylos is once again far more plausible than the route from the wrong Pylos.
Kyparissia really has to be Nestor's Pylos.
