Sorry, nothing to do for now.
New engine needed.
You can only send link from KM to another browser supported.
(These are: PaleMoon28, Basilisk, Firefox 60+, Chrome 48+ and Chrome clones).
The most lightweight things I can suggest are The World 7 and MyPal (PaleMoon portable and XP-compatible fork) or NewMoon (another XP-compatible PM fork with portablemode-launcher).
