that would be fine, as long as the seller was required to leave their feedback prior to the buyer. There would still be wiggle room by the small percentage of idiot sellers who ruin it for all the good guys. I have seen that option on feedback before ' post feedback once other party posts feedback' - i cant remember if it was only as a seller i saw that option ornot. I dont sell often on Ebay, so i cannot fully remember the options there. But i buy often enough, and i dont think the option is available for the buyer.
