Before we even get to New Business, this year's meeting will consider the Business Passed On (warning: PDF) from last year. The only changes to the WSFS Constitution that can affect next year's Worldcon are the items on the Business Passed On. No, you cannot "suspend the Bylaws" and pass "emergency changes" to the Hugo Award rules that take effect immediately. The WSFS Constitution is deliberately designed to prevent people from rushing headlong into making changes like that, and there's no way around it. (If you think that's bad and there should be some way to Change Everything Immediately, consider what any particular group of bad actors who wanted to wreck everything could do in a single year.)
Before submitting business, read the Main Business Meeting page which includes the submission address and also the Guide to Business Meetings page with more in-depth material. You'll save yourself quite a bit of time if you read this before you go haring off with assumptions about how things work or what the rules are.
I seem to spend a lot of time telling people variations of, "You know, if you actually read the rule in question [reference here], you'd know that it doesn't work like you're speculating it does."
