Problem Installing Windows 7 via Boot Camp

I’ve recently created a DIY Fusion drive (240GB SSD & 1TB HDD) using the core storage commands on my mid 2012 MacBook Pro, I’ve restored from a time machine backup and everything works great. Now I’d like to install bootcamp (Windows 7) on it, but I’m afraid it messes up the Fusion Drive, any Idea on how to do it?

This is what I get when I run diskutil cs list on terminal:

Edit: FIXED I’ve tried to do it via BootCamp, I get to the Windows installer without any problem, I format the BootCamp partition but it still says that I can’t install Windows on it (error 0×80300024). How can I fix it?

EDIT: I’ve installed Windows 7, but when I try to boot from the partition I get a “no bootable device” error

New Question:

What if I just swap the drives and leave them swapped? Does the SSD get slower if put in the DVD caddy? Because if not it is probably the best and easier solution.
