I think it is good to discuss this in detail and see if a significant enough portion of the community is interested. I know I could personally get a fair share of miners to back this (fair share meaning not near enough to matter.) At the same time companies that are invested in ASICS and people who have bought them are going to probably spend a fair deal of coin going as far as to pay off the development team not to alter it.
You say you want the developers help, but I see no mention of this on the litecoin talk forums? There is a whole discussion about going to N-factor that has basically be let to die.
This is going to involve a great deal of community support and discussion. You will need to be open to changing your initial ideas and finding some compromise. (Perhaps with enough discussion a compromise can be found that satisfies both GPU miners to keep it decentralized and ASIC miners to keep the network robust? Honestly, this is going to require some time and work.) As a result I find it foolish to declare a block to "fork" this.
I do believe if enough effort and conversation happens there can be enough improvement to the litecoins that maybe we can make this coin serious enough to be a BTC competitor; but someone is going to have to garner support and dedicate a ton of time. And you are going to need some support from the development staff, even if you move forward without their blessing.
Either way, good to see a conversation started. In my opinion this has a long ways to go before it will be a success. We will see how much work you and the community are willing to put in to this. If you are serious, you might want to kiss your life goodbye for a while

Even if just from keeping the conversation going and promoting.
Anyway, I look forward to hearing your plans in more detail; and I strongly recommend that we look for some compromise between ASICs and decentralization if this is serious.
