I believe you can have the wiki closed if its the same subject but abandoned with only one page, and have it redirect to your wiki.

Go to Special:Contact for more guidance from a staff member. Don't go and do the actions below until you get the say-so from a staff member with more clear instruction and they are there ready to pose as a witness to the consensus of the deletion. So here is the full journey from my experience:
 * The process is posting a message on the mainpage, forum and to the last editor / the founder / admin of most senior position as to closing the wiki. (Note that you may become an "editor" at the wiki if you don't do it in less than 5 edits.)
 * You mail the staff member who already sent you the first message a reply stating that you have done the above with links to each place you have sent a message
 * Then you wait a week and its done.
