One consideration I can see for this... How is the @sps.dao Staked SPS handled in terms of calculating the total Staked SPS for a quorum vote of Proposals and Preprosals?
Moving from 2mil to 30mil would add an additional 1.4mil required minimum Staked SPS vote to reach quorum (5% of total Staked SPS).
I think this is easily dealt with by subtracting the SPS.DAO staked SPS from the "total Staked SPS" number used to calculate quorum... since SPS.DAO is not a voter... but the holder and implementer of the votes.
Otherwise, this makes sense to me :)
