Like I said I am not worried about this build being "gimped" as the 32pt remix will be more along the lines of what you are suggesting.
Stopping at 6 rng / 2 fighter for a while though to consider what will best from 9-20 (may need to re-roll as went Law-Good originally and would rather re run 8 lvls than 16 if Ichoose barbarian over pally etc)
Also there is nothing wrong with splashing it just isn't my thing. And I do understand the pros/cons that you listed for levels splits and splashes etc.
I was just adding my input from a similar build perspective. That it is possible to have an enjoyable/successful character built in a similar way.
