The advantage of emulating the existing HW is that you don't have to write all new firmware w.r.t. the calculator functionality. If you start from scratch, you have to also add every bit of functionality that would have been in an original calculators ROM.

I think DB48X is the sort of project you are thinking of. As I recall he found it was not possible to get the functionality desired working with the SM emulator platform so the code base is new and will run on multiple platforms (including SM).
