Here's another approach - I had been listening to YouTube recordings of David Klavins' open-frame Una Corda piano, so here's my early work on a preset with that kind of a bell-like resonant open sound, based on the Bluethner. The mid-keyboard and the bass still need a lot of work, but the upper end is getting there.
As I started messing around and changing many different settings, I got a long way away from the Bluethner Daily preset, all while watching different YouTube videos of the David Klavins piano. Unfortunately, the hammer sound on the different videos varies immensely. And that's just the straight piano, not even including the different felt inserts that he has available to put between the hammers and the strings.
In any case, after messing with it for quite a while, I present a small version of the Una Corda that perhaps someone else can tinker with. WDCO, it only has spectral modifications across the whole piano, and I still do not have the ears and the understanding to work on a note by note basis. In any case, it did give me some reason to play with overtones and begin to understand them. Perhaps someone can help me "tune this" and get a more realistic hammer sound, as on the real piano, forte and mezzoforte has some presence to it, similar to that of a regular piano, while played at piano is quite soft and almost bell-like, as if you are hammering on a harp with a soft rubber mallet.
I would love to hear someone else take it and refine it a bit more. Here are some videos from YouTube that have different-sounding pieces played on the Una Corda:
