Good luck, sounds like you are getting close! However, I believe you need to substitute like for like (that is, butter for butter, oil for oil, wax for wax), So you can use a mix of cocoa and mango butters for the total butter amount, and a mix of hemp and sweet almond oil for the liquid oil amount, but the beeswax amount should stay as it is, assuming you like the firmness and feel of your sample. What
@bookworm42 said above is great advice, especially about taking it slow and changing only one thing at a time (although I can't say it's always easy to rein myself in and experiment calmly and methodically!).
If you'd like a hands-on, trial-and-error way to adjust the feel of your formula, you can use the old Soap Queen trick of putting a regular metal spoon in the freezer for an hour or two, and then using it for a consistency test. Once all your ingredients are nicely melted and mixed together, dip a frozen spoon into and out of the hot mixture. The cold metal will harden the coating on the spoon right away, and you can try that bit on your lips or hands to see if you like how it spreads and feels. If it's too hard, add more oil to the base mixture; if too soft, add more wax (we're talking small amounts here). Of course, you'd want to measure what you add each time so the formula you end up with can be reproduced. This works great for lip balms, so I guess it should work for lotion bars, too!
