Sawzall Table

anyone mount a sawzall under a table like they do jigsaws? I see a cat on youtube that had a jigsaw table with a reach-around arm with blade roller bearings up top to keep the jigsaw blade perfectly centered. I don't see why it can't be done with a sawzall. I want to build one, at least try so if anyone has any suggestions or bettery yet plans, please post up.

I'm thinking I could use a long blade, have the rollers adjustable in height up to 4-6" and depth up to probably 12-18" depending what material I have laying around for an arm.
