You think I can adjust lookup gap with a knc titan for instance?
no, but with a specially designed (futureproof) Scrypt-N ASIC. It's absolutely possible to design one.
and this is why I don't like people claiming that Scrypt-N is ASIC-proof. Nothing is ASIC-proof.

It's gonna be expensive to build it, even if it can do LG.
