I wouldn't expect the cogged belt to work well. The teeth would still cause jumps.
Now, if you came up with a way to grind the teeth off. That might work.

I would like to have both the drives in my HP 9895A working. Since flat belts for old equipment are becoming nearly impossible to find, has anyone had success replacing a flat belt with a toothed? Either by reversing the belt or by also replacing the pulleys? Or by the installation of an idler pully to correct for belt stretch?
