Super cool work. I love seeing this direction taken all the way to hardware.
I'm a big fan of KANs. The really seem like the start of something big and new. We've got a couple of papers out and in the works on KANs. The most relevant to OP's is this one: https://arxiv.org/abs/2512.15742v2
Searching around github and found someone has put up a github repo with a Julia implementation of the article here including FPGA implementation of a KAN MNIST classifier in Verilog. https://github.com/philtomson/KAN_LUT

And we just put up a general primer on KANs on YT: https://youtu.be/wgcSsJ69x1c?si=fiUl1YGTgaTt_bn9 Fun stuff if you want to get into the weeds.
And if you are really interested in KANs, you should really check out Ziming (KAN creator)'s blog: https://kindxiaoming.github.io/blog/
