Another can-I-wear-this-suit-jacket-as-a-blazer question (with photos)

Hello, Everyone.

While I know that this issue has been addressed previously, I wanted to post some photos (below) of a navy wool suit separate jacket I recently purchased at a very attractive price. I very much like the way the jacket fits, but the matching pants are absolutely massive (this is the subject of another thread). Could this jacket work as an informal blazer to be worn with chinos (not with the jeans in the photos)? The weave is fairly fine, and there is a very slight sheen to the fabric. Might it work if I changed the buttons?

Thank you.
