Try this and experiment with the settings ....
Image > Adjustments > Black & White (The Keyboard Shortcut is CTRL+ALT+SHIFT+B)
One of the built-in presets may do what you need ...
or save your custom settings a preset for future use.

MY preferred method is a bit long winded but I learnt when I used to d Band W photography on film and has a bit "scientific basis".
The method is also "non -destructive", an approach to high quality image correction that many professional photographers prefer. Its also slow and tedious considering the adjustment that are available under the adjustments menu it s also demands a bit of Photoshop knowledge (i.e. advanced user)
the steps are Open image, open layers palette.
1 select adjustment layers new , curves (or levels for a slightly simpler version) call this layer colour adjustment.
2 select adjustment layers new , curves (or levels for a slightly simpler version) call this layer tonal adjustment.
3. select adjustment layers new , hue (or levels for a slightly simpler version) call this layer desaturate.
You will now have a layered image with four layers.
The principle is you adjust your colour to greyscale rendition with the colour adjustment layer, tones values with the tonal adjustment layer and desaturate the image to greyscale with the final layer.
the next step is to desaturate the image with the (top) desaturate layer (double click and set saturation to 0).It will be flat and generally unappealing, just like a conversion from colour to greyscale
You will need to adjust this flat grey image in the following steps.
the next step is to desaturate the image with the (top) desaturate layer (double click and set saturation to 0).
now you can adjust the three colour channels individually in the curves adjustment box (this is the science bit). by isolating the colour (opposite) you can change many greyscale values , that is if you wan to lighten the reds, use the reds channel or the opposite colour in the hexagon colour models. Play with this until you are happy
in the next adjustment layer you only ads the RGB composite channels. This will allow you to adjust every tonal value from the toe to the shoulder of the tonal curve.
The top desaturation layer does get any adjustment (besides the desaturation).
The beauty of this method is you can refine your conversion without damaging your original layer.
If any one is interested in a full tutorial on this technique and i will see if I have time to write one up. The write up can have a bit more colour science and some screen dumps for clarity.

I traditionally used a modified version of your method using two hue/saturation adjustment layers, the top layer set to desaturate, the bottom used to adjust the hue.
Your method give much more control and much more nuance. That being said, I learned my method long before Photoshop added the Black and White mixer which does much the same thing, but with even more control.
I didn't mention the adjustment layer method because the original that rflorencio linked to was almost entirely made up of shades of blue and there was very little to adjust. I was afraid that other methods would be overkill.
Good to mention nondestructive editing, which I am a big advocate of when I'm not knocking out an answer without thinking. I should have suggested using a curves or layer adjustment layer along with a desaturate layer.
You mentioned doing up a tutorial. Let me strongly encourage you to do that and post it here as an article. You might even compare your method with Photoshop's B & W conversion dialogue and point out the strengths and weaknesses of each approach.
I much look forward to seeing it.

To be honest I can't compare (from experience) I started using this technique in PS 5 or PS 6 for some reason and never felt the use for any of the other adjustment tools in Photoshop. Curves in conjunction with this technique is so much more powerful than any other set of tools and with few exceptions the only tool to use for colour correction (IMHO) , except for the selective colour tool which seems to have fallen out of favour ( and only used by old pre-press pro'). One vote of encouragement is all I need to write the tut, now I will need to find the time … keep an eye out.
