I'm not sure I see the point.
Is one investor's allocation expected to make other companies' stocks a penny cheaper than they would otherwise be? Are hedge funds, algorithms, and high frequency traders going to let that penny mispricing persist for more than a minute? Is that going to change the external world for the better, or even affect the companies involved? Is there something about the companies you trade with that makes them less evil or destructive than others?
Is owning shares in the companies you trade with really going to make you rethink any purchases, or will it become a (faulty) rationale to justify more spending? E.g. "I own TM stock so if I buy a new Toyota some of that profit comes back to me." or "I own shares in Gap so by buying fast fashion I'm supporting my own investments." If you want to rethink purchasing behavior, why not just use Mint or Personal Capital to analyze your spending categories each month, or to identify specific transactions you regret?
An additional problem is that your AA is probably loaded up on consumer staples and consumer discretionary. Are you considering your consumption's impact on the suppliers of the companies that sold things to you, such as raw materials, agriculture, transportation, business equipment and software, energy, etc? E.g. what about Mosaic, a company which supplies fertilizer to the farmers who sell the food to the wholesalers who pay the transporters to deliver the food to the grocery store where you shop? How many levels deep do you go?
