Hey grrl! Of the topic of shorts, but staying in cycling gear

I want to have zippers put across the center pocket of most of my jerseys (store bought). Do you see any problem with that? I have a friend that's a really good seamstress. She said she'd do it... just needs a little guidance as cycling jerseys aren't her normal forte. She did do a geat job removing the sleeves on one of my old ones. Looks like it came that way...
