You appear to have totally missed the point that the passport expires before his extension of stay, and the he does not have time to get a new passport (ergo the op needs to check when his extension actually ends)
very true, but an extension of stay can not be issued for longer than the validity of your current passport

I believe you misunderstand the process.
You get an extension up to a year OR for the validity of the passport (if it's less than a year)
When you get a new passport they will transfer the extension stamps to it
BUT
they will not give you the time you lost because you're the one that applied with a passport valid less than a year
You now have a new expiration date for your extension (which as you say is May) and that will be your yearly extension renewal date from now on."

Terminated does not mean cancelled.
Plenty of horror stories of people not cancelling Ed and B extensions and then being charged overstay when they apply for a new extension
As you have not yet recieved your work permit, guessing you are on a single entry Non-B, if so, just leave the country without a re-entry permit and it will be invalidated. Then enter visa exempt/waiver.
True(ish), it is invalidated but not cancelled, but if you ever want another extension again, there will be major problems if you have not cancelled the previous extension
There is no requirement for it to be "about the same time", as long as a transfer of over 65k per calendar month is done, that is fine, the date of the transfer is immaterial
You have to apply for a 7 day "extension denied" extension and then you MUST leave the country, so your plan is highly flawed.
I am pretty sure that now you can have more than one employer on a work permit so possibly this might work;
Add new employer to work permit
Get termination letter from old employer
Get immigration paperwork from new employer
Go to immigration and cancel old extension and immediately apply for new extension
