In two words: Yes...(edited LoL)

Reason # 1: Never go on a trip without a spare uniform. You never know when that cup of coffee is going to find itself onto your shirt.

Reason # 2: How would you lug your Case around without a rollaboard?? And no...the wheeled case won't fit in the RJ

Reason # 3: You can't fit a pair of sneakers, and your toiletries, and your clothes, etc...into "something rather small..."

Reason # 4 and most important: You will stick out like a dumby, and be pointed and laughed at, as you should be LoL.

There's a reason our luggage is fairly standard across the board...it's because that is what the job calls for. Get a good quality rollaboard and flight case.
