I don't think it's just the display code. In the WP 34S (and 31S) we have two number formats: BCD and binary integer. The BCD format just isn't suited well to support other bases then 10. (It's based on decima64/decimal128 which encodes three decimal digits in 10 bits).

We would have to introduce another (binary?) number format to support your suggestion. But live is short and flash is full...
