It is certainly doable but I'd suggest you think it through. If you are thinking of moving the track, you may have issues with attachment hardware on the top of the transom - getting to the inside for nuts and washers could be real challenge. Also, the traveler/mainsheet fiddle could interfere with the rudder. If you really want to move things, consider using a bridle for the mainsheet and employing the vang to help with keeping the boom down when needed. Take a look at the Catalina 22's and 25's as an example of the way they do it. Their traveler is short (and raised above the tiller)but might give you some ideas.
