The optimum fighter-bomber tank buster should use disposable weapons which hinder performance very little with mountings that add little drag. The fighter should have high performance and good protection and damage resistance.
The Panzerblitz II (varient of R4M) and HVAR weapons were both excellent for this. Both were accurate weapons which were mounted on small racks which had minimal effect on performance. The Fw 190 used it well, likewise the F4U could carry 8x 5" HVAR. Though it didn't do so (to my knowledge) the P-47D should have been able to carry a similar HVAR armament. (much better than the 6x 4.5" rockets carried in the highly performance degrading 3x cluster Bazooka tubes -M10 rocket launcher-) The P-38L could carry 10x 5" HVAR or even up to 12x (rather poor) M10 4.5" rockets, but the liquid cooled engines (albeit 2 of them) would still be too vulnerable compared to the single R-2800 or BMW 801 of the others IMO. Though the F4U also had vulnerable oil cooler which would be a disadvantage.
The Hs 129 may have been better with some decent engines. With some 1,000 hp class engines and it's moderately low wing loading it would have been fairly able to evade fighters. (I prefer the 30mm and 37mm cannon as thy still leave decent performance, unlike the 75 mm gun...) The centerline mounting was good as well. (I'd say the single cannon is better than the Stuka's or Il-2's 2x cannon of similar caliber) It was probably the best dedicated ground attack a/c, but needed to be developed better.
The fact that there are 2x engines and both are radials is very good for survivability, along with strong airframe and good pilot protection. (and no vulnerable rear gunner to be machine gun fodder for enemy fighters)
There were still other relatively low priority radial engines that could have given the 129 sufficient performance (albeit all at larger diameters than the tiny 14M, weight would be a bit more too) The Gnome-Rhône 14N, Bramo 323, BMW 132, and maybe some others would fit the bill.
