Thanks guys! Test-wired it up, works like a charm. Only change I made to Spidey's advice/ Strantor's dwg was to put the 'pushbutton' on the neutral lead, and use the 12/8/4 side, since it wired easier.
But I have to order new pushbuttons anyway, so I'm thinking I may just do it 'right' with the 'Delay OFF' Macromatic and NO buttons, and return the $12 fake Omron to Amazon.
Either way, thanks a ton, I learned a lot!

 

That will be 50 bucks the invoice is in the mail.

Seriously, glad to help and glad you learned something.
