Why not move the Inaugural season patch over to the left side?
That's where the A/C is located.
The Inaugural Season patch is located more above the shield logo, whereas the A (no C!) is further offset to the side. In theory, there's room -- but I suspect the league might regulate what can be put on that left shoulder.
There are definitely standards about size of numbers on the back and arms, size of letters in the name, and more. Wouldn't be surprised if there is a standard for patches, though I haven't personally seen it.
Some teams have worn patches on the shoulders, but there is history (and possibly requirement) to put the SCF patch on the front. Also, perhaps the Knights are not interested in re-locating the Inaugural Season patch out of superstition or another reason altogether.
I think the Inaugural Season patch is cool (and often hear lots of conversation about it), and it's a bit of a shame there is no way to keep that on throughout the SCF.
