well on the 0-4-4 version, the bottom edge of the stock pilot is the right height to catch and couple an LGB hook ( its not prototypical in any way but its functional and clearly desinged this way
--haven't figured out how to fit anything else without chopping-a real link and pin would work -a kadee might also
on the 2-4-4 versions-one can fit, without alteration, an LGB loop-(sans hook) -or a slightly less obtrusive, but not as good for pushing against another loop, one can use the very old style round loop into the pilot-they both will fit into the pocket in the pilot (cowcatcher)-this will catch a hook-(the 2-4-4 pilot does not have the same function as i described above for the 0-4-4 version)
also if you have them-the LGB snow plows for the moguls will fit onto the 2-4-4- version pilot wheel-the plow rides on the pilot wheel arm-not the chassis
and, you will need the piece designed for this to fill the gap between the boiler and the plow-its a small deck that slides into the chassis-and has trimmed corners so the plow can swivel
the plow will accept an LGB knuckle
if appropriate to your RR, they can improve the look of the forney imho
hadnt thought about the pilot not having the strength as you mention as i run short (3-6 ) trains but it could be an issue i suppose
