I neither have tested karma patched hostapd, nor packet injection support of built-in wifi.
Even if this would work, a second wifi interface would be needed to carry out meaningful attacks, but atraching one is impossible in USB device mode.
Short answer: No.
Pi Zero isn't the proper platform, nor is it the aim of P4wnP1 to bring up a WiFi exploitation framework.
A Pi2 or Pi3 with two alfa adapters (RTL + ATH9K) would better suite this needs, software stacks to do this are on the web.
