Hey Max :)
Better than Dash?? Man, I like Dash. Bitshares is a pretty awesome platform, you might want to check them out too before you get too deep into the R&D of your own blockchain. Adding native support for new coins is not as easy as it sounds though, so I have to say no to that for right now. It involves a lot of research and developer time, support from the community of that coin, etc. Check out Bitshares though, I'm sure you'll like what they've built so far. :)
