Except that it isn't a RISC you have just invented the Burroughs B5000,
circa 1960 (and continuing to this day in the Unisys A-series machines).
Integers are simply unnormalized floating-point numbers with zero exponents.
No type conversions, except there is an integerize instruction used
before storing values that are declared to be int-s.
