I have a neutral Tharja (+1) an am wondering if I should inherit her bladetome to a +spd -res H!Nowi? Oh code this would be for a flier emblem, who would also have S!Camilla neutral (or a suggestion) and Valter (or a suggestion)
If that Tharja is a 5* merge then I wouldn't do it, Grimoire is completely fine on any team and will grant a better score if used on Arena.
Then again, +Spd is the only boon I would consider for the blade build together with Fury, Swift Sparrow or Life and Death; but I doubt it's worth sacrificing a 5* merged Tharja, especially if you don't have another unit with Hone Fliers aside from Nowi herself.
Now that I think about it, I may put life and death on H!Nowi because of how low her def and res already is, but +spd H!Nowi has more speed than neutral Tharja, and the +1, as I remember it (I got both back before or during spring heros), only gave her hp and atk. But I do have a -atk palla that I care less about.
Edit: for refrence:
Ultimately, only you know if it's right for you. I'm likely about to fodder a 5* +atk Tharja for her Raudrblade+ to my Leo (in addition to Close Counter), but that's because I just tinkered around with my reserve teams and created 10 highly viable, all 5*+ teams, and none of them seemed to want or need her (One generally wants to put Ephraim + Nino or Eirika + Linde alongside other partners who support them, particularly bait units).
Infantry Blademages aren't all that good anymore imo, and Tharja/Katarina are the worst of the bunch, as red is the worst color for mages in the current meta (I'd say Nino > Linde > T/K). If you have less 5*s though, maybe you should just promote a different Tharja.
It's worth noting that with access to Flier buffs, H!Nowi will make significantly better use out of Blade+ than any infantry mage. +6/+6/+6/+6 makes a huge different in damage output compared to the usual +3/+4/+4/+4.
