They will get made, as New Haven is a very strong road for Atlas. I don't have a problem with them because Atlas is advertising them as a fantasy scheme. Where I have I problem is when a manufacturer puts out a fantasy model and promotes it as authentic.
New Haven did run the TM-1 and TM-2 demo models and contemplated putting an order in but never followed through. The Atlas scheme replicates the FM artwork that was proposed to the railroad. So while prototypical, it never was applied in practical use. Similar to the 50' checkerboard boxcar scheme and the black/white/yellow EP5 (although an EP5 did physically get painted in the scheme and wore it for a day or two).
