@noClue, your screenshots with Papirus look good. Papirus would also match the choice in MX.
Anti wrote some time ago that he doesn’t want to increase the icon size, because the menu will not fit a netbook screen.
Anyway Fluxbox isn’t the default WM, it would be nice to have clear icons there though. But the user is invited to customize it.
More icon themes I like which have PNG icons:
