539/Education IRA Question?

[ZeusDMAN]

I have four children. They each have a 529 savings account plan.
Separately I have 3 Education IRAs.
I want to close the 3 Education IRAs and transfer the money to the 529. No issue with that, I know I can do that.

Question:
Instead of transfering the $ this way
Child 1 IRA -> Child 1 529
Child 2 IRA -> Child 2 529
Child 3 IRA -> Child 3 529

I would like to do this
Child 1 IRA -> Child 4 529
Child 2 IRA -> Child 4 529
Child 3 IRA -> Child 4 529

Is this doable, legal? Any issues?

In other words, I want to take the 3 education IRAs that I had setup for three of my kids and fund the 529 savings plan for my fourth child since the other 3 kids have well funded 529 saving plans.

Thanks for your help.
