Hello, I'm wondering if there are some ways to hard wire or mod the logic board of a 13" Mid 2012 MacBook Air (820-3209) to boot from any custom made battery.

Basically tricking the SMC to not validate the battery. I do not want to use SMC bypass since that will defeat the purpose and the performance of the laptop will diminish by using SMC bypass.

Is it possible to solder few points in the logic board such as the "System Power Mangement" that will signal "High" or "Low" and tricking the SMC to boot in perfect condition (Not SMC Bypass) from a battery without validating the battery?

Have a look at the schematic and boardview of the particular MacBook Air I have, I attached a zip file which contains both.
