Hi Lars, you would not be using a lamp, just the splitter cube to provide 3 light paths to mono cameras with an appropriate filter for each.
I suspect the biggest issue would be light loss and possible refraction artefacts caused by the splitter. And of course finding a cube big enough for the purpose.
My project was a straight through path to the camera but a reflective path to a guide cam. Any star in the field was therefore a possible guide star.
The other option was to use one of the new SLT cameras, mirrorless technology to provide a lightpath to a guider but I have not got a spare camera with that technology to cannibalise to repurpose.
