IMHO, the better move would simply be taking anything of value from SLC, pre-104, and porting it to Bitcoin.
Please let solidcoin bugs die with solidcoin. Don't port them to bitcoin, please
I don't even know if there's much though, it seems to me, in a cursory understanding, that Solidcoin is architecturally broken, because the author doesn't seem to grok why certain decisions were made in Bitcoin and reversed them anyway.
So why do you want code from solidcoin?
BTW, almost all changes in the solidcoin codebase (at least what he made public) where part of the re-branding, you know, changing "bitcoin" to "solidcoin" all over the place.
