I don't think so.  We have fought many years to get closer to IEEE 754 
conformance.  I don't think we want to throw that away without a good 
reason.  "I want to use the binary format but I don't like what it does." is 
not a good enough reason in my mind.  For one thing, I'd want to see some 
performance measurements.
