It's a good alternative, Presto
but the strength of Khumeret lies in the fact that you can target those well hidden support pieces, like Autumn for instance,
or the ones which are hiding behind a LI fig
which is much harder with Bakus.

Khumeret can also deal potentially more damage than Bakus.

Your suggestion is OK
I just prefer to have two "complementary" figs
instead of two "similar" figs.
