You're likely right here, combining two trust systems does add complexity without solving the core problem. While browsers requiring CT was a great step forward, it's surprisingly under-utilized by orgs. I wonder if this is due to limited tooling for log interaction, or just general lack of awareness?

It's pretty widely used; orgs that have security teams with more than a handful of people tend to be monitoring CT for their own names. Could it be more usable? Yeah, there's probably more than one startup in there. Have at it! You don't need anybody's permission to build something like that.
