I was in your shoes about 2 years ago. The beer turned out fine.
I brewed a double batch, split it into 2 fermenters, pitched generic dry ale yeast in one and dry lager (by the same manufacturer) in another.
The ale tasted like ale and the "steam" beer tasted, well, disappointingly just fine (less esters than the ale, so simply put: a quieter flavor profile).
I told someone with more experience than I about this result and he was surprised. "I've gotten some terrible off-flavors doing that." he said.
So i say, go for it, brew your own beer. CHEERS!
ps Liquid yeast contributes much more to a beer's final profile, and can be more tempormental...
