Welcome to Pond Boss, Roost and Boo,

Since it is obvious that you are doing your homework you may want to be informed that "wipers" are often referred to on this site as striped bass hybrids or "SBH". If you research a little more you will find dozens, if not hundreds of posts on feeding your wipers.

In answer to your question, "will they take floating food".

Wipers or "SBH"--Yes, Always
Smallmouth Bass--Maybe, Sometimes
Walleye--No, never (at least I'm unaware of this working)

I'll defer to someone else to address your questions regarding whether or not this particular mix has potential.
