From what I've seen, there's a copper heatsink attached to the LED cluster that's the light source for the projector.
It looks bespoke in terms of assembly, and there's a top board to remove too with a ribbon cable feeding the projector. Looks pretty tight around this area, not sure you could change anything, and it'd be a rework job as far as I can tell after having a quick look at fitting a different mount to the base, but now I'm just going to pick up on their existing M5 fixings, as I don't want to disturb the internals.
