How do you want to do this? I think there will be a problem with the procedure call standard/argument passing. Presently, we pass FP arguments on the stack. That should be considered nonsense for a hardfloat ABI, but now it is quite practical for transition to a softfloat ABI because it does not require a change. But unfortunately FP return values are presently passed in the floating-point register F0, and should be passed in r0 or r0/r1 for the softfloat ABI. How do you plan to solve this problem?
