This was actually done in some early DEC Alphas, I believe.
OoO engine were able to issue address calculation from loads (if address register is ready) ahead and thusly when real load instruction execute the data is already in cache or closer to cache.
It is really easy to do, actually. It can even simplify page fault handling in CPU.
