Can I swap a Shimano HB-TX505 QR 100 mm with a Shimano DH-3D32?
I'm trying to replace the front hub from my Ghost Kato Pro 29 with a dynamo hub and I'm not sure what dynamo hub fits. I've never tried anything like this so any tips are welcome.

It'll fit in your fork but you'll need a new wheel built up around the dynamo hub.
Since the hub dimensions are different (flange sizes, offsets etc.) are different to your HB-TX505, you'll need different size spokes. And hence you'll be building an entirely new wheel.
You could use your current rim, sure, but at that point you may as well build a whole new wheel around the DH-3D32 and then have your HB-TX505 wheel as a spare should you ever need it.
Thank you for the info. Is there another dynamo hub that would be a better fit/replacement?
Unlikely since dynamo hubs have quite a bit of chunky internals with all the windings/electrics so they tend to be thicker by default.
Also spokes come in +/-1mm sizes, so you'd have to find an exact match like-for-like in terms of hub dimensions if you wanted to reuse everything from your current wheel.
