Do you think if I bought a bag of ice, poured it into a ziploc, and added salt, that I would be able to keep the mix at a lower temp for longer?

What is ideal on day 3 or 4 IMO is more like figuring out a way to refreeze the frozen item (ie: Fresh saline from a freezer/dry ice/add more ice) or ensure that you've continued to maintain a frozen climate inside that portable frozen environment (ie: a separate cooler that you don't constantly introduce higher ambient temperature air by opening and closing).
Adding salted ice around a juice is a kiddie science experiment method that can be used to make slushies, so in theory it can help to refreeze something by dropping the temperature when creating saline, in exchange of making the ice melt faster. This can potentially be problematic if you're saying ice is hard to restock, but this is a potential solution if your frozen thing is thawing even with the ice around it and you still have plenty of ice.
I'd also be curious about a single cooler situation where if having the saline cooler packs or salt water bottles at the bottom and regular ice on top is more advantageous over just one or the other (saline or ice packs).
