I'd like to snag the whole set, if they're priced more reasonably and go mainstream (and international).

I get a funny vibe from this offering, as if the figures are being offered grudgingly. It's strange. Why does it seem so hard to convince toy designers to stop producing weirdness and just give us the things that we want, that we've been waiting for?

This is ridiculous, both the 28$ price (I think the Batman TAS toys are far cheaper and actually have accessories) and locking them behind a streaming service paywall. Even if I wanted to subscribe, I am in Hungary and cannot subscribe to their service.
Ah well, this is what forces people to just wait for copies leaked from chinese factories on ebay.
And yeah, as others said, it is ridiculous they don't give them any alternate hands or weapons. WW without her lasso or Hawkgirl without her mace?
I honestly would not be surprised if they re-released these eventually in the Batman TAS line. They already released Superman and Lois Lane after all, as well as Supergirl and Live Wire.
