If you really need to that would probably be fine(but only if you're direct driving your centers). I just see so limited downside in going without bearing blocks. If you have the resources to spend on completely custom gearboxes then it's not going to take very long to make 8-12 973/1323 bearing blocks. Especially now with the new WCP gearboxes you can shift the resources used to make the gearboxes over to making bearing blocks that improve your consistency and efficiency.
