This is possible, but it will be a lot of work. What you would need to do is create custom decorated bricks without decorating them. This will only work for "Version 2" bricks in the MecaBricks library. You would basically follow one of the custom decorated brick tutorials, but ignore everything about actually decorating them.

When you create your bricks, they will be found at the bottom of the list in a category called Custom Bricks. Is it possible to do? Yes. Is it practical? Probably not for more than a handful of pieces. It would be nice to be able to favorite parts, but that would be something for the next iteration of MB or beyond. Cheers!
