I have two FAS 2240-4 NetApp's that I configured the same. Both with 10 disks assigned to each controller with 2 spare disks per each controller. I now realize that the second 2240-4 should have been setup to have 18 disk assigned with 2 spares to controller 1 and 3 drives to controller 2 with one spare.
I am not using this second system but I need to change to this configuration. What steps do I need to take to destroy the second aggregate and move the drives to the first controller?

You need to reboot your second controller, and go to maintenance mode to re-install your base system.
You could also create a new aggregate with the 2 spare drives and move the vol0/root volume to it, but it is harder to perform.
On your second HA controller :
- disable HA with cf disable
- go to maintenance mode using CTRL-C
- reinstall the system (using the right option which is "install a new system" I guess, I'm not completely sure.

Move one spare disk to controller 2 (so you'll have 1 spare on ctrl 1 and 3 on ctrl2)
Create a new raid4 aggregate on ctrl2 using 2 spare disks
Move the root vol to this new raid4 aggregate (this requires a reboot of ctrl2)
Destroy the original aggregate on ctrl2 (assuming you don't have any important data left in it - you did say it's unused)
Reassign the freed disks to ctrl1, leaving yourself 2 spares in ctrl2 (one as a real spare, and the second one to convert your raid4 aggr to raid-dp)
Hope that helps.
