I don't believe so.

The issue is that x87 is 80bit floats which is awkward. As such, it still requires dedicated hardware.

Intel has proposed and abandoned pushing a new x86 architecture [1] which tweaks x86 instructions to fit better with the reality that everything is 64bit now. Part of that proposal was to make x87 work with 64bit floats instead of 80bit floats (which would have allowed it to share the same floating point units as the SIMD instructions).
