I'd suggest buffing LFs and bombers thrust speed to over 200 (but I have no idea how much over). So LFs could intercept bombers trying to punch through by speed, or ones trying to flee away. LFs would be able to intercept fighters even easier, but not to win them in 1 to 1 (in case of pilots with same skill). Further balance could be achieved by tuning LFs guns speed up/down.
Side-effect would be longer lifespan for bombers. Average bomber pilot is just a free blue atm, at least from my point of view. We are losing new players at that point, as many of them start with bombers and get frustrated too fast.
Another side-effect would be LFs and bombers can flee away when VHFs start ripping them apart and no LFs on other side to intercept.
