Try and see. Balanced should make this setup work. As long as you have the cables what's to lose?

From a technical standpoint, I don't see any problem doing that.
The balanced outputs of the LP5.3 have a 100 ohm output impedance, according to Stereophile's measurements. Four meters of cable at 47 pf/ft represents a capacitive reactance at 20kHz of about 13,000 ohms, which is negligible in relation to the 100 ohm output impedance. (If the capacitive reactance of the cable were not substantially higher than the phono stage's output impedance, the upper treble would be rolled off).
Inductance and resistance are almost always insignificant for line-level interconnects, and the balanced configuration should provide good noise rejection.
