I think mostly will be Asuna due to how close between those two are, I was thinking of Nodoka and Yue too but it mostly no due to Negi rejected both of them in chapter 137.

As for the Touta, I really have no idea about it but I guess maybe will be no Touta in the Negima ending timeline because Nagi was saved after the fight in chapter 138 and 139 (Well we already know about that in the Negima ending) unlike in UQ where he still being controled along with Negi, so there was no reason for Touta being created (I said it because it never mention what was happened to MotB in the ending), plus we haven't seen any alternate timeline of Chao other than the third timeline (The one that we know and brough Asuna back to the second timeline) so I think my statement was mostly true, but of course this is just my wild guess so I may be wrong.
