I also have a tool to generate a tool to generate code to calculate LFSR, and CRC which means you can have a module that can calculate any CRC polynomial on the fly. This tool generates a code that calculates LFSRs and derivative products.
If you still need help using the tool or generating s specialised structure, contact me. I tried to make this tool as flexible and understandable as possible.
This tool should solve all your problems (except acne).
