New Features of the Brewing Station

Minecraft has a brewing stand where you can craft potions, but how about adding some updates to it? The first idea I had was a feature that lets you bundle potions. There would be up to three slots where you could place any potions you like. Doing so would create a single potion that combines all the effects of the potions placed in those slots. However, since that would turn a Wounding Potion, for example, into the most powerful weapon ever, the number of different potion types you can place in the three slots is limited to one. For example, if you combine a Poison Splash Potion and a Wounding Splash Potion, the target hit by the potion would suffer both the Poison and Wounding effects.
