`consensus.nSubsidyHalvingInterval` for mainnet in [chainparams.cpp][1] can be decreased to 195000. This will reduce the number of halvings from 34 to 14 and subsidy will be 0 when it becomes less than 0.01 although not sure if this will be a soft fork.

I doubt there will be consensus for it because all the [projections and predictability][2] about bitcoin(currency) would be affected by this change. Maybe everyone can agree with this change if most of the miners start being 'compliant' like one of the coinjoin implementation.
