Accidentally did this in a blitz game.  Any thoughts on this?   

1. e4 c6 2. d4, d5 3. exd, cxd 4.  b-d3, n-c6 5.N-c3?!(didn't mean to do it but maybe there are possibilities?), nxd4 6. bxh7, e5.   

black looks to have a slight edge.  I looked at f4.  But, that didn't seem to promising.  So maybe 5. b-f4!? 

I am almost certain this isn't sound. BUt, I will have to run it through my computer.  It seems to produce some interesting positions.
