DS26C31 Driver Question

I have an application where I am driving a large capacitive AC parallel termination with a DS26C31 with 33 Ohm series source termination.  The signal is a 5 Hz 50% duty cycle clock.  I inherited this design and don't have the ability to modify the hardware.  Because of all the resistance in the loop, the edges rise/fall sharply but only until they barely cross the switching threshold at the receiver.  Then the large cap (1000 pF) begins to charge and the waveform transitions exponentially until the cap is charged.  I have an option to use a parallel driver from another IC in the source hardware to effectively double up the drive capability.  Both drivers are driven from the same internal clock signal so skew is minimal.  Since both drivers have 33 Ohms in series with each output, is there any kind of reliability or other long term issues that I would have to be concerned with?
