The wire would have limited current penetration due to skin effects even at the
frequency a telsla coil works at. The coil Q would go through the roof. The q
would then be limited by the capacitor Q dielectric losses and the resistance of
the leads to the capacitor to the coil. There is also a limit to the amount of
current a superconducting wire can carry before it goes normal and the
superconducting state braks down.
