Dunno if this has been done before, or not. but timeline wise for Ranma it takes place during the Neko-Ken training and near the end of the First episode of Exodus in the Thundercats timeline. Basically, during the training Genma thinks he's doing the training wrong and re-reads the pages, but now another set of pages are stuck showing a weird design to be drawn for the user to be in. the spell activates and sends Ranma into the Thundercats timeline where when asked who hurt him, after they get him to calm down, Ranma said his poppa. well, the thundercats decide after that to Raise him.
all I can think of is the basics for 2 arcs. The first is during his time on Third Earth learning from not just the Thundercats, but their allies Willa of the Warrior Maiden Tribes, Hachiman, the Robears, Snowman from Hook Mountain and Mandora the Evilchaser. age wise for the youngest Ranma is 6, the thunder Cubs are 10, and the rest between 18 and 30. Tigra and Panthro being the 2 oldest.
the second arc begins just before the beginning of the Ranma series. with Ranma (16), Wily Kit and Cat (20) being sent either by Mumm-rana's magic, Panthro's modification of the Time capsule or Mumm-Ra's magic. the former 2 to help Ranma get home to learn from his own time with Kit and Cat joining their friend in exploring, the latter because Mumm-Ra believes by taking Ranma out of the Picture, he will have an easier Time taking out the cats. this arc may end up having them going to Jade hearing of a werecat community when they see The diggers as they enter the Amazon Village. (the gold diggers crew are there exploring rumors of what they thought was another were community. in the ranma timeline he'll find out that the Warrior Maidens were the ancestors of the Joketzoku, and that Hachiman was Nodoka's ancestor. thus why she carries the blade. Ranma will be carrying on him a Token from willa's tribe that Cologne will recognize as an amulet for their Allies and the Thundercats Symbol on his Shoulder of his clothes as a sacred mark. yes, Ranma will fall into a spring. Drown Female alien catgirl. hint hint.
