2014 Macbook Pro retina No power button

[Mac-N-Sauce]

OK, have a liquid damage 15" retina. the only thing wrong with it is the power button. Have any of you guys had any experience with fixing the power button circuit without just replacing the keyboard or top case.
I am still a rookie so I do not know if this is a stupid question. Just seems like a lot of extra work for just a power button.
Thanks
