I believe the fighters and bombers got engines of the same quality, so this would only help if it means replacing the Blochs with more bombers. A gamble if we get the exact same MS-406/D520 programs as OTL, but certainly doable if we unfuck the fighter situation without any input from Bloch.
It's probably excessively cautious/restrictive on my part, but much like some users who dislike an engine company that suddenly moves to radials instead of Vees and reversely, I feel like Bloch's inroad into the fighter market was inopportune in 1934.
Bloch clearly was inexperienced in the field and while the later types were promising, one can only wonder how much was lost by doing engineering hours on the Bloch fighters instead of the bombers. The MB-130/133 series were overly conservative and a focused effort on bomber developments may have hastened the switch to MB-17X design principles, thus helping both the 170 series proper and possibly obtaining a much better 130 candidate than the one we got - which forced France to wait for the LeO 45 and Amiot 340/350 prototypes for proper B4 bombers.
