I'd suggest not to change it. Since BTC's success has proven that ASICs are good, LTC can follow the same trajectory: to take off further.

BTC is exploring on the moon where no one has been before. Being number one means BTC has to innovate in order to continue its success. LTC has been a successful follower so far. Being number two takes less market share but also less risk.  In almost any market, there's always room for a number two, a follower, who doesn't need to be too innovative.
