The one thing about using juice is that it is likely to add another , say 50 points of sugar to your mead, so if you use say 2 lbs of honey per gallon (US) and you dissolve that honey in apple juice (as an example) then you will have about 70 points of sugar from the honey and 50 points from the juice , and so a starting garvity 1.120 - or a potential ABV of more than 16%. If all you want is the buzz from the alcohol, you have it, but most mead and wine balances at around 12=-14% ABV... So, you may want to consider whether you want to reduce the amount of honey in such a batch to perhaps 1.5 lbs/ gallon.
