there is now a VSTi version of a Kawai K1:

I asked for a VSTi like this a decade ago or so, now there is one. I very carefully recreated it by analyzing every value of every single parameter and did a lot of A/B tests against the K1m that sits on my desk, the effort was huge but at the same time, it was a lot of fun.

I have blog about it which covers a lot of the K1 aspects in a very great detail. I even desoldered the Wave ROM and dumped it by using an Arduino Mega.
Feel free to read more about it here: https://www.nilsschneider.de/wp/kawai-k1-vsti/
Let me know what you think

Best,
