I don't yet have any any other 4/0 lugs so I've been drilling through and modifying these proprietary ones made for Anderson connectors. They're not exactly straight but contact seems pretty good. Thoughts?
I would say 'maybe'. My concern is that the odd shape of the lugs might be lifting them just enough to reduce contact. You definitely want check them when under load and make sure they are not heating up.I don't yet have any any other 4/0 lugs so I've been drilling through and modifying these proprietary ones made for Anderson connectors.

4/0 lugs really need to be hydraulically crimped to cold fuse strands and lug body togetherUL listed 4/0 lugs are $5. And a hammer crimper is $20. No reason not to do it properly.

I agree with UL lugs being $5 and to hydraulically crimp, not hammer crimp. Appears in the OP’s pics, the crimp is hammered.4/0 lugs really need to be hydraulically crimped to cold fuse strands and lug body together
I just want to add that if the load is small, the voltage drop may not show.It is very easy to check voltage drop across the connection using a voltmeter, (multi-meter).
This will work, but I notice that hydraulic crimper is in metric. If you buy SAE wire sizes like 4/0, you may have to go one size underneath on the dies. That will make “Wings” on each side. I see nothing wrong with having wings.and a hydraulic crimper:

Bare copper may work, but I recommend the ones I used that are tinned:alright, i ordered more lugs (these):
