I thought you were the one coded the PoS in NXT. As far as I know at least the first version of NXT's PoS is a direct clone of PPC's with some modifications, appeared lacking a good understanding of the security involved in PPC's PoS. Cunicula instead always wanted a 'hybrid' system involving proof-of-work in security, whereas PPC's security is 100% proof-of-stake.
That said, you are certainly welcome to try some new ideas in the following versions of NXT.
