7i73 keyboard firmware in 7i90

I am wondering on the possibility of putting the matrix keyboard decoder like the 7i73 has, on the 7i90 (as a serial device) and expanding it from 8x8 to 10x10 or I guess 12x12 would be possible on one connector. I'm not interested in the LCD driver component.
I would like a couple MPG encoders on another connector though.

I looked into the possibility of me doing this but ... wow I downloaded the software to do fpga work and that will take a long time to figure out if ever!

Could anyone help me with this request?
Thanks

You could implement the keyboard scanning in software with the matrix_kb comp and use the
standard 7I90 sserial remote config. Its probably not too hard to add a MPG option

Yes I guess I could.
It just makes the HAL code huge/bloated.
I wish to use the panelui component which takes 7i73 scan codes.
I can use matrix_kb to convert to scan codes but it about doubles the amount of HAL code and signal names I must make up that need to make sense.

The 7i73 just doesn't have enough I/0 for my panel.
