You can definitely try the Latvian gambit against e4
It follows:e4 e5
Nf3 f5
It's a happy go lucky type of opening,either it would give you a good space advantage(f 5) file while your pieces would get active squares air it could just crumble your position as you tend to lose centre and get cramped up,...all and all you should at least try it!
Evans gambit, max lange attack and the double scotch gambit
as white that is
Marshall Gambit in the Spanish? That stuff's like 8 moves deep... only works if your opponent knows the theory too
