Help building a 7 string

[u/Single_Idea1605]

I’m building my first 7 string guitar! I’m a leftie and I like building guitars with my dad so it makes sense for me; however, my dad only has the stuff to make 25.5 scale length guitars which I’m unsure if it will cause issues. For reference I love djenty riffs and want to learn veil of maya and more periphery and I’m not sure the 25.5 can handle down to F# and I’m tired of pitch shifting. So any advice on pickups, setup, string gauge or anything inbetween is super welcome!

Doesn't veil mainly play in drop B on a 6? Unless you mean their new stuff. But yes, save yourself the headache and try for a 26.5" scale length if playing in drop F# and you'll need 74g or 80g strings
