I doubt if it is a good idea.

I think that there should be a small book when the program plays moves in 0
seconds and a big book when the program read the book but does not play the
moves in 0 seconds.

I saw cases of big tactical mistakes by program because of a mistake in a book
happen and it is easy at least to prevent it(if we know that a move is good and
the program evaluates it as a blunder we can put it in the small book).

I see no general advanatge for tactical play in comp-comp games.

I am sure that a lot of lines were developed by masters but it does not mean
that the masters did not use computers to help them.
