Not really, because there's a significant tradeoff of time vs gold. You can minimize time, or you can minimize gold, but for the most part, not both.
If you have full lvl 3 Training Fields, you probably have more gold than time. If you're in that boat, this is the rough guide I use:
1-12 basics, nonmatching uncommons, basically whatever low level trash I have clogging up my inventory till it's all gone. Crafting a bunch of basics is superfast and if you've been farming snakeskin you have more shards than you'll ever use. Ever. Even if they don't match, it's only a 1 EP difference.
From wherever you stop there, to 25, Uncommons (silver star). They're faster to farm than snakeskin and cheaper. If you want to minimize gold, then stop using uncommons at 15 or thereabouts, because the upgrade costs become unbearable for what you're getting from them.
Snakeskins are your best bargain if matching up to 60; because fusion stones can be hard to come by and can't be bought (though I suppose you could buy a ton of Enchanted Chests if you're rolling in gems, but let's assume you aren't), I use Snakeskin up to 66. But again, to minimize gold you'd stop around 60. Snakeskins are your best bet even if the elements don't match, since it's so expensive to craft all the other duals, but in that case I'd only use them up to around 42, and then probably fuse/buy Dark Prince chests looking for 50s.
The rest of the way fusion 50s and fusion boosts (obviously, matching only).
I expect someone has figured out what's really optimal, but this works pretty well for me.
