It is against Wikia's Terms of Use to copy content from one wiki to another as you are doing. At the least you must provide attribution so the edit history is not lost, and you must also differentiate the two wikis.

I think you are confused about search ranking: if the content is not as good then the higher search rank is probably a result of the better URL, so assigning that URL to your existing wiki would be a far cleaner way to get the traffic going to your wiki when people search the subject.
