Can I put the inline assembly code as function argument string?

Question

Assume there is an example as below:

pragma solidity >=0.4.11 <0.6.0;

contract C {
    uint b;
    function f(uint x) public view returns (uint r) {
        assembly {
            r := mul(x, sload(b_slot)) // ignore the offset, we know it is zero
        }
    }
}

Can I move the "r := mul(x, sload(b_slot))" as an input string of a function? something like

pragma solidity >=0.4.11 <0.6.0;

contract C {
    uint b;
    function f(uint x, string memory assembly_code) public view returns (uint r) {
        assembly {
            string_to_assembly_code(assembly_code);
        }
    }
}

Call the function like C.f(3, "r := mul(x, sload(b_slot))") Because I cannot determine what calculation method I would use when deploy the contract, I would like to send the required calculation formula to the contract code for simple calculation. Is it possible to do it?
