Have you considered a hybrid HW/SW approach where the DAC only accepts double rate DSD, and the driver on the OS upsamples everything to double rate DSD?
You can probably take advantage of the higher processing power of the host. For example, on a music only PC you could dedicate both CPU cores to upsampling each channel :-)
I must admit I am not a big fan of FPGA filters - not a criticism of what you've done, just concerned about implementation trade offs compared to host based DSP. A conversation I know we've both had in the past.
