Yes, isn't that exactly what https://github.com/llvm/llvm-project/pull/128942 does?    You would link with `-Wl,--page-size=1` and then you could get arbitrary sized memories.   

You currently need to use LLVM tip-of-tree to try out this flag.   If this backport is landed it would end up in the next 20.X point release.
