You are mixing up integer register size and instruction length. RISC-V has variants with 32 bit, 64 bit, or (not yet fully specified or implemented) 128 bit registers. RISC-V has instructions of length 32 bits and, optionally but almost universally, 16 bit length.

The E version only has half as many registers

Ah yes, I misunderstood the original comment as implying that RISC-V C had 16 bit register length, rather than opcode length.
