Yes, it's possible.

But do we want to? Remember that QStringLiteral today has a drawback: if you 
unload the plugin it came from, any left-over uses of it may crash. That's one 
of the many reasons we don't unload plugins, but other people might.

Requiring heap storage avoids that problem. And if we know that it's always 
heap storage, we can also simplify our memory management code by not having 
immutable d-pointers either.
