I don't really think it is worth generating these mnemonics. A lot of the words in that list are really common words so you're making it harder for yourself by re-remembering them in mnemonic form.
I think you should remove all the words you know first, as this will make it much easier to remember. After that if you want to use the mnemonic approach, then if that works for you then great.
Although, I learned most of the weird ones by just playing against a computer which used them a lot. Eventually you remember them all. Incidentally, this way you actually learn a couple interesting new words. Three-toed sloth anyone?
