No "Perfect Storm" scenario likely here....this is more of a case like Iris and Karen from 1995, where the weaker storm ultimately hit cooler waters and was sheared apart by the larger, stronger system. The remnant circulation may become obsorbed, but it's not likely to do anything like the so-called "Perfect Storm" did 14 years ago.
Interesting to note is that such TC pairs -- or triplets, if you include Meena from a couple of weeks ago -- can help excite an equatorial Kelvin wave propogating across the Pacific Ocean. They don't think that'll happen here, but it is certainly a possibility. These Kelvin waves are one of the primary triggers for El Nino events...so, in over-simplified terms, strong activity half a globe away can, 6mo-1yr down the line, help to limit our tropical cyclone activity.
It'll be interesting to see if this actually happens, but I'll defer to the experts and not call for it right now.
