Truth be told I'd recommend the inverse. Make a new Doubles team more focused on synergy beyond just spammin' Earthquake. Weather, quirky gimmicks, more complex (and therefore more effective) Doubles combos... try t' get crazy with it. Doubles is some damn-good fun 'cause you do far more than just run goodstuff and spam the most effective attack(s) mindlessly. Ya can pull off cool combos like Beat Up + Justified, Skill Swap nonsense, Water/Volt Absorb + Surf/Discharge, SwaggerBerry, etc. which're otherwise impossible in Singles.
Let your creativity get t' work.
