That’s so cool!

Reading these comments first, I assumed you were using a variant of Spartan 6 LVDS TDC trick which allows up to 200 Msps rates. (https://sps.ewi.tudelft.nl/pubs/Homulle15fpga.pdf)

But this is a really interesting use case as well, and something that could be used for a 16 channel logic analyzer with analog recording support like the Saleae Logic 16 Pro, but without expensive ADC from Analog Devices.
