I think since the overall measurements are the same as current fixture, it will fit fine…the only aesthetic difference is that the bulk of the new fixture is at the bottom, closer to head clearance for people moving under it. If that feels right, then go ahead.

The frosted panels on the light you’re considering seem like a good fit with your frosted doors. I wonder though - how would a different shape look? As Susan points out, the bulk of current & new fixtures is at the bottom. I’d want to see what a wider & shorter light would look like - balance the size & shape against the center height & full width of the palladian window above the door. I’m looking at you dining light to right in photo. See how the shape of it flows with the same shape window in that room? Try a visualizer if the lighting site has one - put the light in your photo.
