Ghostblood activities in stormlight arc 2

I think it’s very likely that in stormlight arc 2, the ghostbloods will use hemalurgy to collect surges.

My rationale for that is that we know mistborn era 4 will be in space, and that Kelsier is looking for a more practical method of worldhopping than using shadesmar.

From what we have seen, the surges seem to be the most effect method of doing this, with Ishar using them to bring humanity to Roshar.

My guess is stormlight arc 2 has the ghostbloods collecting the surges with hemalurgy, and mistborn era 3 ends with them figuring out how to use surges for interstellar travel.

Given how I highly doubt Kelsier wants Retribution to win, as that would threaten Scadriel. I think the ghostbloods will probably play a role in arc 2 similar to the one they played in TLM. Being allies to the main characters. I think they’ll steal the surges from either the fused or possibly even Odium-allied voidbinders bearing corrupted spren.
