I think time would be well spent in the 3+ list; whittling away the obscure or veritably unusable. The remainder would serve as a good base to employ in padding the character count of a various paper. Irregardless of context, I'd be curious if there was a brainless way to integrate such M heavy words into an article without it appearing obviously forced. Otherwise this is basically a discussion of learning to use a thesaurus and/or working on ones vocabulary. A better use of ones time would probably be to hit the GRE word bank.
