Try creating seams based on edge angle, then UV flatten with those, then UV Layout the result with scaling according to size (some check there dont remember exactly the phrasing).

I am aware of such thing, but I am not using it. Per VOP on shader was just, you know, thinking out loud, what could be cool and all.

At any rate, many manipulations in UE can be done using GPU at shader level, i find it more efficient to work in such way (with limitations and such, thats not the point). Imagine VOPs running on shaders in SOP, rather than being computed by CPU and be geometry-time? One can dream.
