I would like to not increase the cap. The alternative of decreasing the years slightly, leaving pos the same and taking the masternode rewards from the years.

   Coins produced            PoS          PoS rewards      Masternodes    MN rewadrs
1   50,000,000             20%          10000000                      2%            1000000
2   61,000,000             10%             6100000                      1%             610000
3   67,710,000             5%             3385500                   0.5%              338550
4   71,434,050            2.5%           1785851.25             0.25%         178585.125
5   73,398,486.375      2.5%           1834962.159           0.25%          183496.21593

I think doubling those masternode rewards from the above 10% to a flat 20% and reducing the total years  instead of 46.
