Hello,
I always used the vanilla potions, or just their improved versions, but recently I bumped into this mod:

The potions here look amazing in my opinion. There is only one problem - once you install a mod that places potions in game and use potion replacer like this, you either need to create altered version with correctly placed bottles or live with the fact that there will be a lot of floating/bleeding potions.
So I thought, why not to use original mesh and only alter it to look similarly to the potion replacer.
I'm not a modelling expert, but it should not be difficult. Just change texture for glass of the bottle, add shape representing the liquid and couple of small alterations to make the bottles a bit distinctive quality-wise(some silver stripes around the bottle of quality potion maybe? etc.).
If one could get permission from the author, the only thing that would need to be done other than the mentioned changes to meshes would be to clean the esp of changed positions of potions in vanilla game and it should be done.
What do you think?
