Probably not a whole lot Santa, at least in regards to AH.
You might try to get Pyro to add some more of the armament options to the 190 G or F, (see Funked's many postings on that) otherwise your best bet is probably the Me410 or the Hs129.
Neither is going to do very well in the AH main arena (or as good a job as the American Jabo's), but the 410 is definitely the more interesting of the two.
It could carry up to 2,000lbs of bombs, and could carry a multitude of cannon options from the MG151/20, Mk108, Mk103, up to the big BK50, depending on how it was configured for a schnell bomber mission or a zeroester mission
