replacing windows on a stucco wall

hi there, i'm working on a remodeling that involves replacing all the windows of the house (15). most probably the owners will choose wooden windows with a fiber glass cladding. in order to integrate the new window to the existing weather barrier, i will remove about 6-8 inches of stucco all along the perimeter of the opening, install the window in the framing, and put the flashing paper as it should go. my concern is how to keep the integrity of the chicken wire for the stucco. should i hammer down the stucco around the opening leaving the wire? i think it will be too much stress for the structure to break it down with a sledge hammer or similar. it might affect the plaster inside, etc. i could cut the stucco + wire, but then i will need to replace the wire and for that i will need to nail it to a solid member, so i should go all the way to the closest stud. and stilll i will need to hammer it down to have some old wire where to attach the new. would a pneumatic hammer help?
