If you have a moving magnet cartridge this is a really bad idea as the added cable capacitance is going to really screw up the high frequencies.
You can get an inexpensive phono stage, very small and put it next to the table then as mentioned above run long interconnects from it to your amp. It is still not ideal but a bunch better then running long turntable cables.
