No, you don't need to alter your crush. Either scale up your volume (sparge volume mostly) so that you can hit your OG, or instead of buying kits just buy the ingredients you need from a recipe.
If you hit 85% efficiency each time, it's easier to just plan your recipe for 85% efficiency. My system is set up for 75% efficiency, so I can easily predict/plan my recipes and ingredients.
