There's just plain going to be times when you have to break out of the dim/unit analysis model. For instance, in fluid flow analysis, what I do, you often have empirical functions...guesswork...it is not at all uncommon to take a quantity to some variable power that might itself be a quantity. There's no way to enforce dimensions on this.
Is this really right? Are you sure there isn't a constant lurking around that resolves all the dimensions properly? Surely, these formulas have to be adjusted appropriately if you use different units. Can you provide a concrete example?
