I don't think "anything goes" would be wise but there may room for an interesting race with very minimal rules. e.g.
1) Total fuel limit (of specified type etc.). Gives all cars equal energy budget to use. Maybe some fuel could be traded for pre-charged batteries for KERS type systems.
2) Size limits. Must be narrow enough to overtake, short enough to fit in a pit box and maybe a height limit too.
3) Safety requirements and possibly a minimum weight to allow for sufficient safety without overly compromising safety.
There would still be plenty of things that could be done that are currently forbidden such as active aerodynamics so the car could actually have one or more rudders to assist with cornering etc. and that wings could flatten into aerodynamic shapes.
I could almost imagine the cars no longer using their brakes before corners but instead increasing downforce enough to take the corner and that increased drag being the only reason that they slow down at all.
