Trans jack for motor stand?

Probably stupid, but here goes. Floor space is at a premium in my garage, I mean PREMIUM. I've got a nice 800lb HF trans jack and I've got a 360 short block sitting on a furniture dolly. I'd like to have the footprint the motor is taking up shared with the trans jack. I've got the tools but before I start cutting and welding and find out the hard way, has anyone adapted a trans jack to act as a motor stand. I only need it for storage purposes, I won't be working on it and if I need the jack I'll remove the motor temporarily. Not going to raise it high and I could replace that whole adjustable table if needed. Obviously not ideal but it isn't going to kill me sitting under the work bench, right?
