As people mentioned, testing your flavors as single will determinate the strength. Nobody knows what you might like. Looking up the flavor notes for the product in question can help sometimes, and giving you an indicator of where to start. However its still up to you to find a percentage you might enjoy.
With that out of the way, since you are not interested in the energy part of the drink, searching for energy drink would yield probably no results. My suggestion is looking at POG or naked - POG clones in the data bank.
Reason is that this, while different profile, more of a “energy” drink you’re interested in, rather than well a red bull/rock star mix.
You could easily switch the flavors and add yours, different percent of course and might it work. Or look at recipes that say cooler and/or summer vape. There might be even some recipes already that include your flavors. If not, at least you get practice and understanding of these flavors and can make the drink based on your own likening.
