Earth's Tiniest Heroes

Question

So, at this point I have two options that will totes affect the story.

I'm either going to make the avengers age jump two years every one in a while (which would be easier) or I could keep them the way they are until the end and then turn them back. If I did the latter, I could make a sequel where they're turned to 8-11 year olds and then another sequel where they're teenagers.
