Mentalism and Water Memory

This is just an idea I have. In our world there is the idea of Water Memory and is popular with some supporters of homeopathy. the principle is that you can dilute a solution of a healing herb extract so much that there is in probability not a single molecule of the herb extract in any one sample of the water but the water retains a memory or imprint of the herb being there and retains the healing properties of the herb.

Now mentalism allows one to both manipulate water (Liquid Manipulation) and memory (Mind Mastery).

Could a mentalist develop a spell list that allowed them to create single dose potions by imprinting spells into vials of water? Essence allows casters to create runes from 3rd level and channelling allows stones to be enchanted using symbols (Symbolic Ways) from 4th level.

Could a mentalist be able to create 1st level spells as potions from 5th level?

I can see that this would make the realm of mentalism much more powerful. The potions are portable in a way that standing stones are not and can be drunk by anyone without skill unlike runes that require a level of education investment.

An alchemist can create a 1st level potion at third level so it would take something away from the alchemists profession if other people could also make potions.

I am a great supporter of players researching their own lists and spells and think it should be encouraged. So we are talking about a fairly big investment in development points as well as time. A 5th level spell takes something like 5 weeks of meditation to research. Higher level spells to create 2nd and 3rd level potions would take at least 3 months if not years.

Would you consider allowing a player to create such a list?
