Plasma cutter idea

I've been playing around with my new plasma cutter and the first thing that I've learned is that I will not be cutting freehand, at least not
any time soon. So I made a circle cutting guide that works really nicely and I was thinking about a straight cut guide, when it occurred to me: instead of moving the torch over the stationary material, how about moving the material under a stationary torch? It would work like a table saw. In fact, how about adapting an old table saw to a plasma cutter?
You could "rip" with it, or use the miter guage. Cutting to a line with a miter guage would be a lot faster than clamping a straight edge with the right offset. Cutting to a pattern would probably be easier with 2 hands guiding the pattern against the torch. Hey - you could have a #5 lens fastened in front of the torch for helmet/goggles free cutting.
It could have a water pan for "swarf" collection & fume extraction would be a lot easier with a fixed torch. If the fume extractor worked really well, you could use it inside! Foot pedal arc control. The torch would have to be easily removed for off-table use.
Limitations: really big pieces of material (4 x 8 sheets or 20' lengths).
But I'm a newbie at this plasma cutting thing and sometimes I get carried away solving problems that don't really exist. What do you guys think?
Thanks, Bob

CNC is not in my future - the $800 I spent on the plasma cutter was at the budget limit.
I don't generally cut large stuff, so if & when I do, a special set up is acceptable. I'd like the everyday small stuff to be convenient. Taking the cutter outside & dragging out a cutting table is the major inconvenience that I'd like to change. But having it inside really depends upon good fume extraction, which is much easier with a fixed-torch cutter. I plan on some experiments with fume extraction.
Today I cut a 9" square out of a circular piece of 3/16" mild steel. This is typical of my cutting jobs, so a table-saw sized set up would be appropriate. Another typical job is cutting pieces out of PC cases, also small enough.
I found that microwave oven magnets will hold down a cutting guide, so that's a problem solved (having to clamp down the guide). The work itself still needs to be clamped & avoiding that would be convenient.
For now I'm going to build a quick-and-dirty cutting table (bed frame angle) and get some more experience with my cutter. I'm kinda' keen on this idea, so there's a good chance that I'll build it, someday. If & when I do, I'll be sure to show it off here.
Thanks, Bob
