Given the amount of content on there, it is likely that it will never be possible to mass import Sensei's content to any other site.
It is possible to dual-license your own content so that it can be added to Sensei's.
License incompatibility is a real shame, in my opinion.
I don't believe license incompatibility is a problem. It becomes when there is so much bad practice around that someone may start to contemplate sueing someone else. But before anything like this happens the social cost of the bad practice would be by far more damaging than any legal issues would be.
And you don't need to dual license or any fancy legal stuff, when you can put your own stuff on several pages. This happened to a lot of Joseki material original on SL, which is now on Josekipedia too. Afaik this is due to Andre Engels who was very active in this area of SL participated on Josekipedia. What all pages are lacking however, is feedback going in both directions. They add variations on Josekipedia, on SL there are some additions and changes too, but basically they remain distinct after the initial input, nobody bothers to edit at the other place. Even where the contributors do overlap like SL and L19, there is very limited spillover.
From the SL point of view, relying on outside links too heavily has one major downside (and it has been pointed out as a problem of SL in this thread). All those links to the interesting XY discussion on godiscussions, articles on gobase or your now abandoned blog around the corner are now without value to either all (godiscussion) or the majority (gobase) of readers. I have no doubt when linking to the BGA page for their book reviews, they will stay online, but many other - mainly the individual - pages are far from sure to survive.
