Possible to partition Bootcamp to SSD on custom fusion drive?

Can anyone advise me on installing Bootcamp on the SSD partition of a custom fusion drive for Mac Mini. I'm not sure how best to get achieve the partitioning of the disks and from what I've read it may be impossible to install bootcamp on the SSD of the fusion drive as it will be directed to the HDD according to how Bootcamp assistant partitioned the fusion drive. What I would like to do is split the fusion drive in half and have Bootcamp installed on the SSD the same way OS X would be, but from what I've read the Bootcamp partition can only installed on the HDD and impossible to partition to the SSD, or at least without having to install both OS on the SSD then split the HDD in two.

I've created a fusion drive with a 250gb SSD and the original 500gb samsung HDD, OS X is installed, backed up and I have Winclone copy of Windows 8.1 ready, I also use Paragon file system drivers for reading/writing between both systems if that is any help to how it could be partitioned.

Can anyone verify that this is it is indeed impossible to install both OS to the SSD in this manner or is it possible to partition the fusion drive as I would like to have it?

Any other suggestions as to how best install both OS is welcome.

I'm still getting 2002F errors multiple times now, sometimes it boots without a wifi connection selected sometimes with. the commands you asked me to run above do they return anything or is that done in the background?

The bless command was just to show you what is done in the firmware on the Mac to allow a network boot from Apple servers. The URL points to the Apple SW CDN boot servers. It is a secure connection in most cases.

In the linked article, if you notice, only WPA/WPA2 networks are supported.

Did the grep return any data?

Firstly if it's late don't let me keep you! I'm running the terminal from Recovery on the Mini itself and the grep commands didn't return anything and as for the bless command it's completely new to me so I'll no idea what I'm doing.

running the bless command you gave me returns with an error with --verbose

Just to note the disks are wiped.

I am in GMT -5.30/-4.30. You being in the UK, it was late for you rather than me.

If you have not yet rebuilt the CS volume, can you post the output of diskutil list in the state they are currently in?

For the bless command you can try bless --info. It provides the current boot ability state. The --legacy* qualifiers are used to support legacy BIOS booting.
