Yet another way to lock the phone??

[typeadam]

OK, this is probably going to sound confusing...

There's a lot of screen lock threads here and on xda but I have not come across one that is specific to what I'm looking for so I'm not sure it's even possible...
So here's my current setting:
- only the power button turns the phone on and off
- holding the end button locks the screen
Here's what I'm looking for:
- 1 press of the power button will lock the screen/buttons and turn it off
Believe it or not, holding the end button for 3 seconds to lock the phone is a time waster, I'd rather just press the power button once and it'll lock it and turn it off. This way, holding the end button will allow me to set it to turn the radio off - like on almost all previous PPCs and virtually every other phone.
I'm not a fan of S2U2 or other programs of the sort.
I know TouchLock and Gyrator have something similar where you can insert the stylus to lock it but I'm looking for simplicity and ease w/o additional programs.
I'm sure that remapping the power button to lock the phone is possible but that won't turn the screen off. I'm looking to do both at once w/ 1 button press.
For example on all my previous Treos (WM and PalmOS), if I pressed the power button it would shut the screen off. If I pressed the power button again, it would wake the phone up but the keys would be locked - just like the TP lock screen...
BTW, if DisableSMSWakeUpEvent worked properly on the Touch Pro I wouldn't really care since the power button isn't easily pressed by itself...
Thanks!
