Nope. The egg's stats are determined when you receive it, so you'll hatch the same five Magbies each time. Your time would be better spent at One Island.
And sorry for not posting in the past few days, but I have nothing new to report. I've saved in front of the purple kitty in Fire Red, but I don't really want to get him as shiny since I don't really care and I wouldn't be able to use him much, anyway. If a shiny one pops up, I'll catch it, of course! (Man, is this thing hard to catch, though! With 1HP, paralyzed, attack lowered 6 levels, special defense lowered by one, 40 turns passed, he still manages to escape my Timer Balls with a single wiggle... >_< Rayquaza wasn't this tough.)
