well for missions, an interceptor pilot wouldn't do you any good, you'd be better off going for the HAC or a second BS pilot , speaking from experience. 2 BS pilots and 1 logistics pilot can run any level 4 mission quickly and without too much danger, hell with good enough skills technically you could run a lvl 5 with that set up (some not all).

upgrading from a drake to a raven is a very nice upgrade especially if you just need to level up a few skills to pilot it well, 6 arbalest cruise launchers ( with appropriate ammo) and 5 Hob 2's or HH 2's really destroy things. ive had no trouble soloing any lvl 4 with my raven, and i'm only at 5.8m sp so i'm not highly skilled yet, T2 tank, and T2 cap modules make things easy.

just my thoughts, hope i helped in some way.
