Just to clear this up a bit:
Yes it would be pointless.
Dropping the temp of a compressed charge by using IC's will still give an inlet temp of warmer or equal to ambient air, you're not going to start freezing things hahaha! Do you realise how hot turbines get? Have you seen one at full chat, the metal glows, so theres no worry of going too cold there.
I can't see how this would damage the turbo in any way whatsoever... it can only spin as fast as the exhaust gases permit, having a longer inlet tract has nothing to do with how fast a turbine spins, as i mentioned they flow massive amounts of air a second. All that will happen will be a cooler charge being delivered into the engine at a lower pressure (Pointless) at the same turbo speed.
Yes he would need deep pockets.
