I suspect this will do nothing except slow your connection down - they'll be storing NetFlow records, no doubt, which basically say "This IP had a TCP connection to that IP and this amount of data went in one way and another amount in the other direction." Perhaps they'll "enhance" this data with a quick sniff up the stack to grep out a URL, and perhaps try and add some form of hardware signature and payload protocol from request headers and DPI. The use of a VPN will obviously mask a lot of the info, though.

If you're really keen on adding load to their work, instead of doing this and wasting your disk space, write a short script to load up random google searches, and then follow links to random results from the searches, with various random header value selections and MAC addresses, and then load it onto a Pi and leave it trundling along. For added fun (& risk) seed the initial google searches with various naughty phrases - how long before someone knocks on your door with a Ram-It?
If you were malicious, connect it to your neighbours open wifi :)
