This sounds like a good idea but in reality I suspect would be of limited use. I would just add more line (use braided line such as Powerline Pro over mono filament for double/triple the test strength), as many fishing hooks as possible, more lures, swivels and sinkers etc. Not having enough line is common mistake.

Without a proper reel and rod, casting becomes very difficult (trying to emulate a proper rod without a reel would just end in a tangle of line mess) so if your not using the following hobo style of fishing;

then a trot line would probably be the most productive way of fishing with as many small hooks as possible.
