What i'd do is get the strawberries, cut the tops off.. Then mash whats left, add pectic enzyme and some ice cubes in a ziplock bag (make sure it doesnt have holes) - it'll sweat a bit, adding minimal water, but better than all that ice melting into the must.
The ice will help keep it cooler, so fermentation doesnt kick right off, giving the pectic enzyme more time to work.
When its practically soup, take the ice out & let it warm to room temp. Add your sugar to SG1.085, and yeast energizer & nutrient. Then i'd probably go with 1122 for a yeast.
I wouldnt actually add any water to the wine at all, just ferment it as it is. Maybe get 2-3 gallons, but it'd be killer.
