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.
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.
