Hello, I recently bought my first nice upright bass. It came with Thomastik Spirocores on. Everything is great although the G is too thin for my taste. Could I tune another D string of the same brand/type as my G?

I don't know enough about strings. Why? not right length?
To tune a D to a G, you'd be increasing the tension by nearly 80%. Not advised. Find a thicker string. This is the first time I've ever heard a bassist complain of a string being too thick, but you know what you like.

Oops, yeah , that's what you said.you mean too thin? but yes. thank you guys.
Just adding a bit to what others have said, the D string would probably break before reaching G.
It's an interesting problem because: As strings get thicker, they get more massive, which requires more tension to bring them up to the same pitch. The only solution is to find a core or winding material that's less dense than steel, so the string can have a larger diameter but the same mass per unit length.
This leads me to ask: Is a gut G typically thicker than a steel G?
