I would like to see alchemy recipes to transmute Orbs of Alchemy into other Orbs with differing star levels, much like the recipes we have for transmuting Radiant Fire Crystals into Shining, etc. However, I think the ratios should be equal to the ratio of the respective energy costs from the supply depot. So:

1 Eternal Orb = 2 Elite Orbs
1 Elite Orb = 2 Advanced
1 Advanced Orb = 4 Simple Orbs
1 Simple Orb = 5 Flawed Orbs

This would make orb drops more fluid and thus more valuable, regardless of what type they are. The crown cost of transmuting could be tweaked to prevent abuse (without making them overpriced), but I believe the ratios should be as above.

I would also like to see recipes to reverse the process: i.e. convert Shining into Radiant or Simple Orbs into Advanced Orbs. (Not as useful for orbs, but more for fire crystals.)
