There is an interesting design at turbo9.org for a 6809 implementation. (impressed by the team BTW)

That is impressive. Not my personal goals, I think -- I am not a C programmer for instance -- but the 6809 was always praised. And of course it can run OS9, which still exists in some form.

Video with very balanced discussion about design choices over here : https://www.youtube.com/watch?v=8ScT86RKopQ

I am not a video watcher but maybe some time I can.

Bitstream for Arty-A7-35 exists so maybe it can be made to run on this : https://machdyne.com/product/kirsch-computer/

Interesting... I will read more on this.

(disclosure I am a total n00b at FPGA, but I appreciate the effort of designing a board).

Me too.

Check out the Machdyne Timeless Computing philosophy to see if this resonates with you.

Very interesting!

WIBNI we could have a hypersonic version of the Dragon 32? Up to 2 orders of magnitude faster... Might even run a version of Lisp for 6800 if BASIC is not exactly your thing.
