I could try something like that, though how I WILD is slightly different then how most people do it.

I don't actually stay fully aware/concious - I let my mind my drift, but I don't let it go to far. Every once in a while I'll bring myself back fully and see my progress of how far into the WILD I am, and if I repeated 2-3 times, I'll eventually feel SP hit. Though doing this does involve a much greater risk of losing conciousness completely, but I'm not the type who can fall asleep focused.

It's usually like

1 - Lay down
2 - Wait for the initial HI and sounds
3 - Once I've got these, I'll start thinking about something, a place, a memory, anything to keep my mind occupied and not focused on the physical world around me.
4 - Wait for the HI to get pretty heavy - this happens when your brain takes over and actually switches what you are thinking about 95% of the time, there's no effort here, no thought, everthing is pretty much auto-played by your brain.
5 - Let my mind drift off into this brain controlled HI, hopefully not to far into the area of unconciousness.
6 - "Snap out" of the HI, check my status - usually I will feel pretty heavy, eye-lids do not want to open anymore - this is good, I am not in SP yet, but I am getting close.
7 - Lay down, and await HI again which will happen almost immediatly
8 - Let my mind drift off again
9 - [repeat 6-8 if needed]
10 - Eventually while my mind is drifting during one of the HIs, I will feel SP begin - it's so noticeable even if you are only slightly concious - sometimes it may even wake your mind up and bring you back to concious. Symtoms may include a "collapsing into the self feeling", or "fall through the bed feeling" with the movie-like visual HI abruptly ending. I'll see scattered traces of color, and slowly fall toward "The Void".
10(optional) - You can actually focus on the SP to make yourself enter the state faster. You won't mess it up as long you can control your emotions.
11 - Once in SP, I'll be in a a black void that sort of feels like I am inside of myself, or inside of my own physical head with inifite depth in every direction. I've gotten amazing hallucinations before. The way to do this is, is to try and open your physical eyes. I guess for me it's just an automatic response because I usually always see my physical room at some point during SP. My mind sometimes, not always, will give me some pretty cool hallucinations to mix in room. Once in my covers were moving like ocean waves, anothertime my wall turned into a black/purple grid, and a hole opened up and I saw some stars, then I saw my living room on the other side of it. I usually always have auditory hallucinations. Sometimes booming noises, something creepy ones, sometimes people talking, etc.
12 - Sometimes, I will begin to feel vibrations, when I do, when they get very powerful, I will try to imagine myself rolling over. It then feels like I roll off my bed, and end up somewhere in my room and my LD/OBE/WILD begins

Step 6 might be difficult the first few times, but eventually you sort of just develope a thing for it

I'll give it ago for more detailed information, but I don't know how much I'll remember from my flucuating/altered areas of conscience.
