In theory probably yes, in practice from what I've heard ARM has some CISC-style instructions — presumably exactly because they offer performance increases.

even without going too-CISC it can make sense to have instructions for popular use cases e.g. ARM has special instructions for optimal numeric operations in JavaScript: https://developer.arm.com/documentation/dui0801/h/A64-Floating-point-Instructions/FJCVTZS and I thought I'd read something about custom instructions in Apple Silicon to optimise virtualisation (i.e. translation of x86_64 executables) but I can't find a source for that, maybe that secret sauce is not in the instruction set
