Anecdotally, many people don't like soaps with high “cleansing number”, i. e. those that are high in lauric oils (coconut, palm kernel oil): they report a harsh, stripping and drying experience to the skin. But not all people, some are fine with 50%. You might be fine, or might not. You won't know until you make a small batch first and test if your skin likes it.
To a limited degree, the harshness of high coconut/PKO soap can be moderated by lye discount (superfat). But here again, it's best if you test it. Too much superfat in recipes with some soft oils (sunflower oil is one of them) can impair the shelf life (worsen issues with rancidity).
