Recasting will probably be necessary in the future, but for how this show turned out, the CGI was borderline-necessary. The S2 finale simply wouldn't have had the same impact with a recast. Even if the CGI was janky, once he took off his hood your brain still got that immediate confirmation that yes, this is 100% Luke Skywalker who just swooped in and saved the day. A recast would've left that lingering doubt in too many people's heads, and no matter who they picked, it's invariable that a lot more people would be complaining online about the casting choice than the janky CGI.

When and if the day comes when classic characters like Luke need to be recast, I think it'd be wiser to announce it in advance, and give fans time to acclimatize to the change.
