nothing for you... But fur many others they couldOK, here is it:
I won't buy a SSD for Armada even if it would come from FFG because it would be either too large or it would be a joke.
As soon as it would become playable size-wise, it would be a joke.
There is nothing in between. Face it.
Would it be ok for you if it would be twice the length of an ISD?
If that were the only option to have a SSD on the table, sure. But I would prefer a 24"-28" version with special setup rules. I see no reason why it can't be made to work.
