The work is already done for you. You can purchase the aftermarket Real Fake Disk.

All the chords of all the songs in the Real Book, 6th Edition are there, and there is a Real Style assigned to each one of them. There are over 400 songs on it, for a little over 11 cents (US) per song.

Since they are made in BiaB, you can change the style, arrangement, key, tempo or whatever you like.

There are a couple of free samples on that page. Look for a linked song title in the right-hand column, and download.

Note: This is a self-serving plug as well as a solution to your problem. I've been making aftermarket products for BiaB since the 1990s.
