I did tooI misunderstood. I thought you were talking for the engine. For the transmission sure. Save some weight and gain some clearance.
I would do it if you can't fab one yourself.I did read that it helps to remove the perches and bolt those to the motor mounts and install the engine that way. I opted for the other route and well, next time I’m attaching the perches first.
The tubular cross members aren’t much $ and I’m inclined to just order one. Jegs has a nice affordable one.

I don't think you can delete the crossmember....
