Multi-Form Technique in Open Legend

I’m curious as to how you guys would mechanically treat an action like this in Open Legend. For those of you who don’t know, the Multi-Form technique is from Dragon Ball and allows a fighter to temporarily split into two identical copies, each having half the power of the original one fighter but sharing one mind. I would guess that the Summon boon could sort-of do that, but it certainly wouldn’t be an exact recreation of the effect. What do y’all think?

I"d probably do it entirely with flavor and Multi-Attack Specialist or just a Multi-target attack.

Conversly you could do it via Alternate Form and have the alternate form have the companion feat, spliting the feats between them, thus each a little weaker, but 2x the action economy.
