What kind of speed do you get as is?

A shorty would help when you put a the stern jack on the drive shaft center line will be lower so yes a shortie will help

A stern jack won't lower the propshaft in positive trim like an extension box does. Two different animals.

That's a long way to drive to try out a shorty, but I am a Fedex Ground contractor. I can get it to you.
