Storing interfaces as void[]

I want to store interfaces as untyped void[], then cast them back
to the interface at a later time. However, it appears to produce
garbage values on get().
Is this even possible, and if so, what is happening here? The
alternative would be a struct { CheckedPtr self; api_fns.... }
e.g.
void register(I)(I i) {
auto mem = new void[](I.sizeof);
memcpy(mem.ptr, cast(void*) i, I.sizeof);
// CheckedPtr includes a hash of fullyQualifiedName
map[i.get_name()] = CheckedPtr!I(mem.ptr);
}
I get(I)() {
// basically cast(I) p
return map[I.get_name()].as!I();
}
