Possible, yes. Difficult, yes. In fact, difficult enough where I am not going to attempt it. You can get equivalent functionality by creating a composite column that mirrors the bool column, marking it as shown in tag browser, then hiding the column so it takes no space in the library view.

(Also, if possible, please don't forget about my desired author and title like custom columns)

As a) this too is difficult with lots of internal ramifications, b) I have no personal use for it, and c) as it can be done with templates at the cost of having a second column, I will leave it to some other developer.
