You can absolutely do that, but you need to make sure that you can reliably start from the same point and have pegs in the material to make sure you have got the same orientation and same spots.
I did those on the Primo as well: Der Froschkönig - Lowrider 3 in Oldenburg, Germany - #14 by Tokoloshe. You can see the very little hole in the bottom right corner where I put a 6mm dowel to be able to accurately cut the second half.
