It sounds like you are combining Alchemy with Runes to mimic (lack of a better word) other forms of magecraft. I like this. How about you use special ink to write the Runes? Like anything related to fire you use ink infused with ashes, or ink with sea salt for water. Could help cover the equivalent exchange, also infusing the ink with your own blood could add an extra kick. Or the blood of others. Or part of your servant, now there is something, especially if they are from the Age of Gods.

What the runes are drawn in doesn't matter. You can gild it in gold, draw it with a finger in mud, paint it in dragon blood, or outline it with smoke from a poor-quality cigarette. It won't change what the rune does, because the magical foundation has been already contacted and the effect is made. You can't "alter" spells like that.
