I hate to say it, but I think your engine will fall out.
I'd rethink those engine mounts. Those welds might crack over time. They will be subjected to torque and a lot of vibration. Besides looking weak, you'll get a lot of noise and vibration without the rubber mounts. Can't you weld the Metro mount bracket to the CRX's frame rail, or at least mimic the shape? The driver's side looks OK if the larger center bolt goes into the frame rail.
But I'm no engineer or expert welder, maybe it will be fine.
