I haven't played too much baton pass this gen, but I'm quite sure that the baton pass set is not right. The main use is on dedicated baton pass teams. As far as "suicide lead" baton passers go, there are much stronger options - you could be passing Shell Smash instead of a measly Calm Mind. You might have some success using Espeon as a baton passing pivot, but frankly I would consider this another option on the offensive set rather than a dedicated baton passer.
As Jukain said, Espeon's job is to reflect dangerous moves, and to sweep right at the end with a LOT of boosts (mostly in defenses, but also in Speed and special attack from calm minds). With this many boosts, resistance to stored power is more or less irrelevant - the only problem is dark types. Up until that point, Espeon is extremely valuable and should not be risked for anything. The opponent might try to wear espeon down, for instance by attacking with potential phazers and taunters, and you need to be as ready for this as you can be. Trying to set up boosts is just giving up precious health on your espeon and risking a crit.
The moveset should probably be:
-Baton Pass
-Stored Power
-Hidden Power Fighting / Dazzling Gleam (you need one of these at least in order to actually hit dark types)
-Morning Sun / Substitute
Keeping a sub up is really important for a baton pass team, as you need to block crits. Calm Mind is best left to something else.
edit: also, some recommended partners would be: Scolipede, Vaporeon, Scizor/Mawile, Mr Mime. You don't need a recipient. Espeon IS the recipient.
