How the hell did that even get there? Even if it somehow fell through the Breach and got lodged in there with Gypsy, it should still be back near the new Breach where they got dumped, nowhere near where the fighting was. Did Firestarter find it in the wreckage and decide to carry it around like some kind of trophy?
At most, two more Jeagers could show up so there could be a whole team of them because it'd be cool. Also the fact that at least Gypsy is manifesting Aura could mean the lot of them could start doing muted versions of Huntsman maneuvers. Because nothing could be more demoralizing to the Kaiju than seeing Cherno Alpha do a frontflip and put his massive metal boot through a Cat-IV's spine.
Those designs are way too horny, I'm pretty sure that almost none of the Jeagers would have builds like that in human form. Cherno Alpha for one would have a build somewhere between Reinhardt from Overwatch and Heavy from TF2, and also wouldn't be a chick, Gypsy's flashbacks have confirmed the big lug as male presenting.
Possibly, though I'll be using my own inspirations.
