If you want to do this this way, do it in hypervisor code and keep feeding AT scan codes to hyperv-keyboard, although I am pretty sure users of French, Czech and other keyboard layouts with numbers in upper register and symbols in lower will have a few choice words for you. If you want real cut-and-paste support in various DEs I'd recommend working with VMware on open-vm-tools package to see what can be shared/reused there. Consider this NACked with prejudice.
