getting people to use the ASK site for purely deterministic and therefore presumably simpler questions seems a good way to go although how you get people to do that I don't know. Maybe refer them back to SSC if its an open ended question? Trouble is you will spend a lot of time doing that.

linking your Ask reputation to your SSC points sounds good if you want to encourage posters here to also post at ask, and maybe also feed back points gained at ask (for replies) into SSC? Probably I am asking too much there.

Perhaps selfishly I will continue to concentrate on SSC so at least I get the immediate feedback of accumulating points for the time I give to it, unless all the 'low lying fruit' migrates to ASK, then I might have to. 🙂 Perhaps that is an intention to clean up some of the white noise of repeating simple questions from SSC?

The big advantage of SSC is that it is much more of a 'debating' format and therefore a better source for in-depth learning.

So please don't take your eye of the SSC ball, but if you need a sister site to combat the threat of StackOverflow then that is a business decision.
