It was probably too soon for Lockdown, as "Basic Becky" is too similar to Zoe who is still pre-heel-face-turn here. In the comics, Lockdown only debuted after Zoe's heel realisation, after she stopped bullying Kamala and joined her friend circle.
Wait, last we saw, Zoe was in Damage Control's custody - what if we're in for a surprise and they merged her with Becky? The MCU does like to subvert expectations and this show has deviated from the comics in several ways already.
