The concept of "punching down" in this context is hilariously wrong. We're already doing something exceedingly verboten as it is; I doubt doing it at Earliest Green is significantly worse than doing so at Peak Yellow. Moreover, as has already been demonstrated by Sun Liling, succeeding at something by punching down doesn't matter much if you succeed in the first place.
Also, we've got a custom order talisman lined up for this job, so I'm not particularly sure why we'd want to go in without it.
Not to mention wanting to maximize our chances of ghosting this job. Someone spotting us is very nearly as bad as being caught directly in terms of consequences. Something I think people are pretty aware of given, bad rolls or not, we were detected breaking into Renshu and Liling's bases.
We only get two fuck ups here(one save for the reroll)* and then we're screwed on market stuff. Not to mention any possible censure from Cai over it. I'm not sure she'd call us on it, but she is big on justice. So it's a possibility to keep in mind.
*Honestly, part of me is wondering if we shouldn't switch out EPC for Argent Soul just for the additional reroll we'd get out of it. EPC's reroll is permanent, so if we could pick up another one from Argent Soul, we'd have a larger margin for error.
