Additional constructor methods for ImmutableMap/Multimaps

Would it be possible to add the following static methods (or similar) to ImmutableMap/Multimap etc:

ImmutableMultimap.of(Iterable<Map.Entry<K,V>>)
ImmutableMultimap.Builder.putAll(Iterable<Map.Entry<K,V>>)

Use case would be where you want to transform a Multimap<K1,V> to Multimap<K2,V>

I'm imagining something like:

    Multimap<Object, String> in = ....;
    ImmutableMultimap<String, String> out = 
            ImmutableMultimap.of(
                    Iterables.transform(in.entries(), 
                            new Function<Map.Entry<Object,String>, Map.Entry<String,String>>() {
                                @Override
                                public Map.Entry<String, String> apply(Map.Entry<Object, String> input) {
                                    return new AbstractMap.SimpleEntry(input.getKey().toString(), input.getValue());
                                }}));
