I would like to request the 190F-8/U1. It would be really simple to add, as all it would require is adding a pair of 250kg eggs and DT's for the wings.
I imagine it would be implemented simmilar to the loadout options for the M3 (ie, all options on one rack), as they only carried a 250kg egg on the centerline when they had 2 250's on the wing, not the 500kg egg like our current biggest bomb for the F8.
While it wouldn't significantly increase the ordnance carrying capacity of the F-8 (only 50kg, or ~110lbs more), but what it would do is increase the number of usefull bombs carried. In most cases, a 250kg bomb is preferable to 4 50kg bombs.
So overall, we gain a lot of versatility that the F-8 has been a bit lacking in, all for a minimal ammount of work, and we lose nothing in exchange. Lot of benefit, no down sides.
