I find it hard to imagine such a situation; it sounds like you are
giving me a proposed solution instead of a requirement. If for some
reason the requirements change and the code needs to load 4096 into
the register, then it is trivial to change the opcode along with the
operand.

Lots of wrong instructions won't assemble. The solution is to use a
correct instruction, which will assemble.

That's totally irrelevant to you issue of incorrectly changed code not
assembling.
