Yes, I think it should be possible without any technological hurdles. It's just some work to set it up.

(DL models are trained with one type of camera and used with another type of camera all the time, and that's sort of similar; plus renderers as used in blender3d are pretty good and they should work well with LEGO bricks which are relatively simple objects; if despite all this it doesn't work you could degrade both the real and the generated images e.g. by quantization, with the aim of bringing them closer together.)
