Underpowered Party

I have gotten slightly bored of playing BG with a standard powerful party and decided to kick it up a notch by playing only the worst of the worst classes ONLY

I decided to create this 4-man party for the job

Wizard Slayer
Jester
Shapeshifter
Beast Master

I am planning on running this party through both BG1 and BG2.

Has anyone ever tried this? Any tips are welcome ;p
