the only time i'll open K7 is when im at least 90% sure im winning the blinds (e.g. at 2/4 full ring).

My VPIP is over twenty percent and my opening ranges go something like this:

UTG: AT+ A6s+ KJ+, 22+, QJs, JTs

MP: add KTs, T9s+, QJo, A2s+, maybe some mid suited connectors

HJ: add K9s, 76s+, T8s+, JTo+

CO: add K8s, 45s+ 86s+, 89o+, T8o+

BTN: add some offsuit aces, K2s+, anything suited or connected thats somewhat decent at all.

This probably adds up to way more than 20% vpip, but obviously you adjust your ranges based on image or whose in the blinds.
