We don’t recommend it. In the world of cooking, this would be like replacing a spice like cumin or cinnamon (something potent used at low amounts) with something like celery or broth (something significantly less potent in the flavour department that is used at higher concentrations in food).
If you were making a curry, replacing a teaspoon of cumin with a teaspoon of celery would be rather silly. You’d lose a ton of flavour from the loss of the cumin, and an additional teaspoon of celery will do nothing to compensate for that loss of flavour.
It’s the same with essential oils; replacing essential oils in a formulation with carrier oils is pretty meaningless. If you don’t want to use the essential oils called for in the formulation just replace them with more water (if it’s a lotion) or more of the predominant carrier oil in the formulation (if it’s anhydrous).
