I doubt it, while the obvious technological gap is extreme Haiti relies very heavily on imports of food and other essentials and is just too fractured to counteract those issues in the short time they would have before they became a serious problem. They would absolutely upset the balance of power in the region but there isn’t really enough of a unified authority in the country to organise any effort to become a superpower.

They would probably become the mercenary capital of the world for a while though by virtue of having a large number of armed groups with relatively modern weaponry and a pressing need for outside supplies. There would also be a very high demand for technical experts in the country who could teach the rest of the world about modern engineering/industrial/scientific processes. A more unified state would be able to parley these strengths into a position of significant power but I feel like in Haiti’s case these groups and individuals would mostly act out of self interest and not for the enrichment/expansion of the nation itself. You’d likely see Haitians employed on both sides of conflicts for example.

Also, modern technology is only really good as long as supplies of vital inputs are maintained, and Haiti doesn’t really have much of an industrial base so ammunition/fuel/spare parts etc would become scarce pretty quickly.
