Huh? Where does it say that a mallocator is required?
As far as I can tell, you could simply do this:
void[] myBuffer = ...;
auto allocator = Region!()(myBuffer);
auto p = allocator.allocate(...);
The default parent allocator is NullAllocator, which does nothing, so
that leaves the management of myBuffer entirely up to you.
