Eelektross could possibly run an effective set similar to yours above, a stall set, though there are better stall Pokemon out there. However with no weaknesses and decent defenses it just might work. Here's a bulky substitute sweeper set that works off eelektross's best assets (its attack, bulk, and interesting movepool.
Eelektross@leftovers
Nature:careful
Ability: Levitate
Coil
Substitute
Thunderpunch
Drain punch
Invest in hp, attack and special defense. Coil will boost attack and defense, allowing you to tank hits. A well timed substitute will allow you to get more coil boosts or take down a dangerous, faster enemy. Thunderpunch provides reliable stab, becoming quite powerful after a boost or two, and drain punch provides a means of recovery.
Hope this is what you're looking for.
