Doing this wouldn't secure LiteCoin's future. It would doom it.
ASIC doesn't mean you loose decentralization. I mine both with GPUs and with ASICs. ASICs are cheaper, faster, energy efficient. The energy efficiency means someone like myself who doesnt own a datacenter with 1000s of AMPs of power can mine 100s of MegaHashs. If you stay with GPUs then in the future only people with lots of time, money, large scale cooling, and power can mine the coin for profit.
Again ASICs means you can mine coin for *cheaper* up front costs.
Again ASICs means you can mine coin for *less* power.
Again ASICs means you can *scale* your mining operation to larger heights without having data-center like resources.
Again ASICs means more coin, for less energy, to *more people*, faster.
ASICs should not be feared.
People do not like that they will have to spend more money after buying a lot of GPUs that may have not yet gotten a ROI. That is understandable. And there are other Coins out there that are still GPU only. So there is no need to throw in the towel. Why not look into up-in-coming coin ideas. Like SecureCoin, or FairQuark. Or some of the N-Scrypt coins.
If you make a coin that tries to replace LiteCoin but is more ASIC resistant you will just... lower.. the difficulty of ... litecoin... hrmm... GO GO GO dam those dirty ASICs for taking over LiteCoin... ALL GPU miners should just leave now! Power to the ... rrr... X11 Coin!? woot!
p.s:
Also... X11!? De-frack? You REALLY wanna name your coin after a monolithic horrible bundle of miss match code that is X11. Not to borrow from the Emacs haters but... X11 is a good OS, its just lacking a Window System. Actually that isn't even true... its horrible. All hail WayLand!
