Hi Dan, I see on the Sigrok wiki that there has been some prior hardware designed with the FT601: https://sigrok.org/wiki/CoLA This uses the FT601 for a host interface, and logic signals are read by an FPGA which can also do multiplexing etc. But if I understood your idea correctly, it is to read logic signals directly into the FT601 FIFOs without another chip, which is a simpler, less expensive design.
Anyway, there is a barrier to using the FT601 chip: "The CoLA does not have integration into Sigrok and Pulseview. This is because the used FT601 driver is from FTDI and is closed source. This is the reason that prevents the software from being released under Sigrok compatible licence." The closed source driver mentioned is D3xx: https://ftdichip.com/drivers/d3xx-drivers/ So we could probably get an FT601 device working "out-of-tree" using the proprietary driver, but I couldn't find a free software library (analogous to libftdi) to drive the FT601.
