I don't think so. If we were making automobiles and our model consumed 40% more fuel than our competitor's, our response would  not be to solve the problem by fitting a larger fuel tank. The stack layout of AArch64 is, as close as we can make it, identical to that of x86-64. So, this difference in memory use is not expected and should be investigated.
