You're asking for the wrong thing. You don't actually want/need the 8 man operations to have mechanics that are clearable with 4 or less players. What you actually want/need is more content designed for 4 or less players. Basically new tier 2 flashpoints and introduce tier 3 flashpoints.

My Wish list:

Tier 2 HM Flashpoints with new mechanics:

Hammer Station

Athiss

Mandalorian Raiders

Cademimu

Collicoid War Games

Red Reaper

Of course, I'd love to have brand new Flashpoints with new stories and new settings, but that will take quite a bit longer. For this, the devs already have the assets in place (script, 3D models, voice work, etc) and only need to work out new mechanics, add a few animations to accommodate the new mechanics, up the difficulty for a level 50.

Would love this as well.
