Yes i have done this mod. Actually about mm 2 days ago. And it doesnt work very well. I cut every 2. It worked good on floppy cables. But for the life of me i kept cutting into the ide cables. Especially the new ones that have super thin cables. It would be much better just to buy the round ide cables. You can buy the 3 pack with 2 ide and 1 floppy for like 4.99 on ebay.
