Alternative Switching

I recently tried to build one of the wicked switches switching options and I found to to be really difficult. I don't seem to have the knack for connecting IC's together. Especially when there's 3. So the idea I had was to use a combination of DPDT and the 4066 chips to do the bypassing. This will allow me to use a cheaper DPDT and still use and LED. I think connecting the DPDT to the controls of the 4066 is a little easier than making a millennium bypass, at least for me.

The idea is this: One pole connects to 9v, the two throws connect to two controls of the 4066 each. This allows the switches to open two paths or the other two paths, making the signal bypassing efficient.

The other pole connects to 9v and one throw connects to the LED. Another idea I had was to also disconnect the 9v from the circuit when the effect is in bypass mode. The other pole would also be used for that.

The question I have is, is this going to work? What will it take? Is this as simple as I think?

Also, the cheapest I've seen DPDT's for is $2.50. I know there's a company in the UK with cheaper, but I'm in Arizona, so that doesn't help. Anyone have better suggestions? The place I've seen $2.50 at is pedal parts plus. Any opinions on that?

Thanks in advance.

That is how I build almost all of my pedals.
Just be advised that disconnecting the power is not as good as it seems. that noisy poping ghost....
