If you are learning from past mistakes of the DPoS experiment then my recommmendation would be to leave the old baggage behind. Perhaps start all existing accounts off at 500SPs.

That sounds nice but it doesn't work as well. The new blockchain needs the financial support of some whales, else it fails. Because someone has to pay for equipment.

@blocktrades already said he is working on a better REP system. My guess is the the new chain as a "carbon copy" of the current STEEM DPoS implementation is just the start.

The implementation and even DPoS itself should evolve from there.

They already are aware that without further development it will fail. This very blog post says so.
