Frame sizing dilemma

Good morning everyone,

I'm struggling to make a decision right now and I was hoping you guys could help me.

So I'm in the process of building a new bike, starting with a vintage frame.
After searching for a while, I've found one incredible frame for sale, full Reynolds 531, in mint condition. It has a classical geometry, with a straight top tube.

The problem is that the seat tube might be too short. I'm 1.78 m, with long legs (inseam is 84 cm) and kind of a short torso. The seat tube is 52 cm, while the top tube is 55 cm ; head tube is 11 cm.
Fit calculators that I've found online suggest that the top tube length would be perfect for me and that a 55 cm seat tube would match me the best.

I'm quite flexible, so I guess I could handle kind of a deep saddle to bars drop, but I'm afraid that setting the saddle to high would push it too far back.

So, what do you guys think? Should I go for it?

Thanks in advance and happy holidays!

PS: I was wondering if I should post this on this section or in the mechanics one. Feel free to move the thread if I'm in the wrong place!
