League Settings - Ideas

I have been in the same league for 8 years now. Its pretty standard (Yahoo), and would like to spice up alittle without rocking the boat in just 1 year. Would love to hear some suggestions.

Current roster size is 15 players, with 1 QB, 2 RB, 2 WR, 1 TE, 1 FLEX, 1 K, 1 D as starting line up. I would be interested in taking out the Kicker and Def. Also changing the TE spot to a Flex Receiver position. If I remove K & D would I just go with 7 starters or should I add more positional players?

Also on playoffs does anyone reseed the standings based on total points?

Thanks for any ideas that you have to offer that I can look at.

Replacing the TE, K and Def positions with three WR/RB/TE Flex positions could be fun.
