i highly doubt that they could have pulled off an invasion of the Summerset isles. For 1 the Altmer have the best navy in all of Tamriel. Second it took Tiber Septim bring the numidium to the Isles to make the Altmer surrender, as he knew he could never beat them there(the Isles). So unless Titus had the numidium hidden and ready to use against the Altmer the invasion would have failed.
