Sounds like an intonation job. You can keep the saddle you have now, so long as the guitar is physically playable at that height, you just need to adjust the contact point of the strings on the saddle until they are in tune. To do this, I place a short length of wire (a cutoff from an electric guitar G string actually) underneath one of the strings at the saddle so that the nylon string only touches the saddle at the wire--the wire is the contact point. Then I tune the string and use a strobe tuner to measure the correspondence between the string's 12th-fret harmonic and fretted note. You'll probably notice the fretted note is not in tune with the harmonic. If the fretted note is sharp, move the wire further back towards the tie block and repeat. If it's flat, move the wire forward towards the soundhole. When you find the spot where the fretted note and harmonic are the same, mark the wire's location on the saddle with a pencil. This is the point that the string must break over the saddle for it to be in tune. Repeat this procedure for the remaining strings, then file the saddle so that it has peaks at your pencil marks. When you're done, your guitar will be as harmonious as possible. I find this pretty tedious but can't think of a better way to do it...
