I think that people are over exaggerating a bit on how good Gekko will be with the Skye nerfs, Skye is still a very good agent, she can and still will be run solo but I think that she might be ran in double initiator comps more so she can use her very strong flashes for well, flashing. I could for sure see a lotus comp where it runs Raze, Fade, Skye, Astra, Killjoy, the lack of a viper could hurt but this comp has a lot of control to take space even without the Viper. I think gekko will have some uses as a jack of all trades initiator instead of being fully overshadowed by Skye but he won't be meta defining or anything, I think he will see a lot more play on Bind, a bit more on Lotus but thats the only real main places I see his pick rate being increased by a good ammount.
