We got different types of bombs, and thats a fantastic start. But we still need to rework how ordnance is selected, and add some more options for a couple of planes to make it great.
1) Keep current arrangment, save for the few odd-balls such as the bombs on the 110 being selected along with the gun package, or the F6F's DT and bombs being on the same selection column. Two options to work with. A) we could have a pop-up inform you when you have slected two incompatible load-out options (say, you try to select DT and bombs for the Hellcat, which interfere with eachother). You hit okay, and pick which one you want. Or B), we could have the incompatable ordnance options be greyed-out, based on what you have currently selected.
Biggest advantage to the second option, is that its pretty strait foreward, and would work better with gun-bomb packages, like on the 110 or the 410.
2) Add more options to the existing planes. The 190F is particularly lacking compared to what it could carry in real life. Give it the 8x 50kg bombs, the 1000kg centerline bomb, 2x 250kg wing bombs, and a single torpedo. The P-38 could carry 4x 1000lb bombs, or 2 2000lb bombs as well, IIRC. F4U-1D should also recieve the 2000lb bomb option. The 190A-5 had an option for wing drop-tanks at the expense of the 2 extra MG FF 20mm's. Considering the 190's rather limited range, it would be a particularly usefull addition, allowing it to carry wing DT's and the centerline bomb.
3) depending on what ordnance options are added, introduce perked ordnance. 4x 1000lb bombs on a P-38 could be a bit unbalancing if left unrestricted, for example. Similar issues might be encountered with the 1000kg bomb on the 190. Would be the most survivable German aircraft carrying more than around 500kg (1000lbs) of ordnance.
