Would this work? Filipino WW2 knife

[Giannis K. Hoplite]

The sword has one basic problem for being a greek kopis or machaira. It is not wider in the one third from the tip. Were all kopides and machairae wider towards the tip? I don't know,but this is what i have seen in all artistic representations and actual finds,with no exception.
Both in art and in an actual sword i have seen handles that are similar to the one the sword has now. Some modification would be needed still,but not necessarily something fancy. Perhaps the blade is more suitable for other historical swords,than the greek machaira.
