I posted just previously on the construction of the KJV - essentially a re translation of the Bishop’s Bible, with scrutiny to those other sources you mentioned, along with some input from Latin and Greek manuscripts.
I didn't see that post-what number was it?
The KJB was suppose to be a revision of the Bishops, but the translators used mostly the Geneva.
Since the Bishops was in the line of the Tyndale-Geneva-AV1611, the differences between them all are relatively minor in comparsion to the changes between the AV1611 and the modern versions.
