I used to play pretty close to this (about 27/22ish)

When I felt ppl started to reraise me light I'd start 4-betting preflop right away.

I think you just have to be ready to go to war with much more marginal holdings. It's the only way to make it tough on them (although this may seem like it's "playing into their game") otherwise you'll get owned hard.

Showing them that you're not afraid of spewing a buy-in or two is very important imo.
