Whoops, that was supposed to be Lon'qu.
Edit: yeah, upon review there's very little reason to do it this way and not with the secondary options. So, it'll be:
Cherche x Henry
Cordelia x MaMU (+MAG -LUK)
Lissa x Ricken
Maribelle x Lon'qu
Miriel x Gregor
Nowi x Vaike
Olivia x Stahl
Panne x Virion
Sully x Donnel
Sumia x Chrom
Tharja x Gaius
The only one of these I'm still somewhat conflicted about is Panne and Virion. I picked Virion because he was the only remaining candidate who could pass down the archer line for Hit +20, but I'm wondering if Frederick wouldn't be a superior option for Dual Guard+ instead.
