I think this would, especially with the upcoming 5th gen aircraft, be an awesome addition to the french tree.
We will lack proper 5th Gen Dogfighters, as the F-35 are held back too much by the amraam and the Su57e would be an amazing replacement. This would ensure that the French Tree remains unique and on par with other nations and their respective subtrees.
Especially the monoton ground lineup of only Leclercs could finally be fixed and a bunch of empty BRS finally filled with interesting and competitive vehicles.
