We also have the fact that Jasnah thinks she can teach Shallan Soulcasting, even though they're of different orders. I believe that surges are mostly identical across Orders, though they might perhaps be used for different purposes. For instance, while Lightweavers seem inclined to use illusions to hide truth and tell lies, I wonder if there might be a way for Truthwatchers to use Illumination to reveal a situation, or call attention to something that might have otherwise been missed. To literally illuminate the truth. Or, if Renarin gets a handle on his Illumination, I think he might be able to use it to show people what his visions look like, which could be very powerful.
