Double or Single Precision?
Is that a 144-pin device? Guessing not
Floating point is done in software on CM0 and CM3 parts.
The CM4F has a single precision FPU that does some basic math functions, the remainder are handled in the library code.
Without some more specific reasoning, it sounds like you need a redesign.

There aren't any that are pin compatible. There are some that are close but have an additional VDD/VSS pair. See the "Pinout compatible" search feature in CubeMX.
