With regards to the 3 cams listed in the OP, there are two different families of lobes in play here, with the Mopar grind using the lobes with the most area under the curve.

The Chevy and Ford cams use the same lobes, with the extra lift for the Ford coming by way of the higher OE rocker ratio.

If you look at the more “entry level” hyd roller lifters, most have .700 or .750 wheels, regardless of the lifter bore diameter.

If someone wanted to use the lobes from the Mopar grind in their Chevy or Ford build...... its no problem.
Just order it up and they’ll grind it for you.

This is not the same as having a .904 specific flat tappet profile in your Mopar, and someone wanting to use it in their Chevy.
The only way that’s going to happen is if the lifter bores are enlarged to use .904 lifters, or a mushroom style lifter with a .904 or larger foot.
