Yep, I'm all for it. However, they would be still heavier compared to equivalents ICEs.

There's no reason to think that will last. The kwh/kg of batteries improves by 5-8% per year, and we've been in the higher end of that range the last few years. Meanwhile, EVs are about 30% heavier. It will take a few years of improvement to make up that gap, but there's every reason to expect this trend to continue.

Also, it takes a few years for new batteries to find their way into existing models. 1.08^4 = 1.36, which means improvements in batteries since 2020 could have made up this gap already.

Yes, sure, batteries are evolving and there are solid state batteries on horizon, though probably very expensive initially. There is also a concept of getting energy wirelessly from road, which could further reduce battery sizes. I'm sure the future is bright.
