Forum:Elemental+Destiny Hero. Can it be done?

Basically the idea is to have your opponent guessing. I run a Dragoon deck with 90% of the above cards minus 3 sparkman, a 3rd prisma and the E Hero Fusions (though we own at least 2 of each of those)

Dragoon works nice like it is. I could ALSO sub. Sparkman for Wildheart and do the same for his fusions. So, yes/no? Ideas?
