Highly unlikely. And it's been beaten to death here.
But, I had a thought. A dangerous thing, thoughts.
If Menard's tooled up for an accurate, modern (pick one) center-beam flat, modern mechanical reefer, tank car, coal hopper, covered hopper, gondola, and I mean modern. Nothing built before the 1990s, maybe even 2000. (I'm kidding about the pick one comment. This is not a poll.)
They pretty much would corner the market on the modern freight cars we are all asking for. And the other companies seem to be reluctant to tool up for.
Might be worth the tooling costs.
And I'm not expecting detailing on the level of MTH. Just accurately proportioned and decorated cars we could use as is with no apologies, and the purists could nip, carve off, offending details, and add their bent wire handrails, and cut bars, etc.
This would all be highrail. Let's not be greedy. If they included a Kadee coupler pad at the end of the under-frames, that would be all we could ask for. Scalers; source your own trucks. Or maybe we could get NWSL tool up for scale wheels for whatever their trucks would need.
And let's have cars that would go around most curves. Nothing much over 60'. No near 90' cars. Menard's is clever enough not to go there in O Gauge, and they shouldn't go there in S Gauge. NO SHORTENED CARS. Proportioned is the word here. S has almost no chubby toys. Except for some later ACG stuff, it is always well proportioned. If you're cutting new tooling, make it beautiful.
It's not going to happen, but I'm retired, and sitting here with my thoughts.
Maybe I should get a dog.
