My reasons for not are as follows
Why??? whats it gaining you. It doesn't get rid of bumper steer it may well add bump steer into the front end that you didn't have before.
The sliding shaft is going to send a lot of shock and vibrations up the shaft and into your hands now that its location is un-sprung and has no shock suppression. Hit a bump and its tire and what ever little absorption the slide joint offers then your hands.
