Just a thought, but what about Joe's Quick Grape Mead? I did a no boil version with 3# of honey per gallon without the final back-sweetening suggestions (although I did top off with more grape juice to make an even 5 gallons) and it turned out great, just like alcoholic grape juice with a subtle aftertaste of mead. My starting gravity was 1.140 and it finished under 1.000 in less than a week with proper nutrients and energizer additions. 18.2% was what I believed the abv to be, and the mead hid it well. Dangerously well.
Anyway, here is the original recipe and link:

Methods/steps
Just finished bottling my first Grape Mead Melomel or Pyment whatever one wishes to call it and it was started on November 4th and is simply wonderful to drink already. It was ready in 5 weeks!
Thought I would share my recipe with you, as it is the youngest best tasting, quick mead I have had thus far. Too bad
It will ferment super fast to dry (about 13% alcohol) because of type of yeast and all the nutrients and natural sugars in Welch's grape juice. It should be to SG =1.000 or less in 14- 21 days max.
Rack to clean carboy over mixture of 6-oz honey, 6-oz Welch's grape juice, 1/2t of Sorbate and 1/2 crushed campden tablet.
It will stabilize and clear fast. Let it clear and set for another 2 weeks and it will be ready to bottle and drink.
It will be medium sweet but smooth and drinkable right away. If you want it semi sweet use 4-oz honey instead of 6-oz / gal.
The only reason I used the Campden (Sulphite) is because my understanding is that using both Potassium Sorbate and Sulphite together will definitely inhibit renewed fermentation and it did for me.
Color is deep red, has nice legs on sides of glass after swirling, good nose and great balanced taste) Just don't tell everybody you used Welch's. I won't. Because the juice is clear to start, clearing is naturally fast, fast, fast.
