In my humble opinion, once the caps reach pack voltage - there is no current drawn through the pre-charge... and keeping the value (resistive) high should not overheat it much in the initial stage of pre-charge - just take a bit longer..

I wondered if cl-30 inrush thermistors would be a good,fast, pre-charge alternative.. I use them to cushion the inrush to the DC/DC - any thoughts?
