I think you might be slightly overestimating leader rifles while underestimating an fg42.
Look, FG42 is good on FJs, because they're better platform to begin with. To the very least you receive ambush bonus. When it comes to Pgrens, they're one of the bad-medicore platforms as for mainline infantry. What you're doing with that upgrade is exchanging leader rifle for FG-42. When you buy the leader rifle upgrade, you exchange 3 Karabines for 3 Leader rifles, having 4 of them in total. That is far far better than 1xFG-42, yet it costs 10 muni more.
45 munition is a lot for winning against rifleman in close combat (you can do the same with leader rifles upgrade too). If sth is underestimated it's the leader rifles. Can someone make DPS chart for both the upgrades?
I think that such an upgrades should be based purely on DPS charts, cause mainline infantry (like Pgrens, marines, rifles, tommies) does not have many abilities (like fireup) to begin with. Ofc, we have to look at auras too, but PE does not have many of them (if any)
