Decided to go with a custom PCB keyboard build to achieve the 15X6 layout wanted. You can remove up to 2 rows and columns from the pcb. https://keeb.io/collections/frontpage/products/bfo-9000-keyboard-customizable-full-size-split-ortholinear?variant=8116065271914
If anyone finds an Access-IS 90 key keyboard, please still let me know!
