What about kickstarting a project for new gameplay system in BG3 which is more alike to Baldur's Gate 2.
It would be real time with rounds and pause system. It doesn't have to be replicated but only inspired by 5e ruleset.

It would require combat systems team, gameplay systems team and encounter designers to create this for Baldur's Gate 3 and be payed. Plus whoever I'm missing.

It doesn't have to be done on launch day. It could be done much later. Launch day is already stressful and tasking for the whole team. smile
