Welcome to Packards. I expect you'll get several opinions on your project, some possibly negative. There are several considerations. Since you are replacing an engine and trans with one approx 2/3 the length, there will be motor mount fabrication needed. Body mods for clearance shouldn't be an issue and even frame clearance, but chances of not having a solid piece of steel on the frame where you need it are good and will be something to consider as to how to make it and not do damage to return to stock. Distance to radiator, steering item clearance may be an issue and drive shaft/drivetrain/linkage mods will also have to be in the budget. A lighter engine/trans may also require some suspension changes as well. There is one other fellow recently posting that is contemplating something similar with a Cadillac engine. I forget which year he has.

Does the engine or car run at all? If it does, it may be just as expensive to change the engine as to repair the original. They are really quite good engines, and if you have it, even the Ultramatic of that year is very dependable if adjusted and driven properly-- although definitely not a race transmission as a young fellow is apt to want. Leisurely is one of the kinder ways to describe the acceleration. If it's been abused and damaged, then that could be expensive to repair and not many places will work on them. If either is a consideration, a stick would be better. If you already have a stick in the car and plan to keep it, a Packard trans adapter to another engine might still be found but possibly expensive if you do.

Depending on what is needed, used and even new components for that series car are reasonably available and may be less expensive than you suspect. There are many here who can give some help as to what may be a problem and how to repair it.
