Just wondering if a 96 blazer motor and tyranny would work in a 95 GMC jimmy

 

yes it will

 

The transmission probably will. The engine, however, will not. '95 == CPI engine. '96 == SCFI engine. While the block can likely be used from a '96 into a '95, the heads on up are different and would need to be swapped from the '95 engine.

 

just have to swap intakes. it will fit and work.

 

Wrong again. The bolts that hold the intake manifold to the heads are in a different orientation (96+ SCFI engine has vertical bolt orientation while the 95 & earlier CPI engines had the intake bolts oriented perpendicular to the intake gasket surface on the head.
