By the way see link below... This is the last outboard and full upgraded version of klipsch speakers I did for a friend of mine.. I have done K-horns, cornwalls, and reference series by outboard premium crossovers in the past, you will see that using all premium parts like this make your original crossovers look like matchbox cars! These were only 2 way klipsch by the way, so no midrange circuit which is even more complicated, costly, and sizeable.. You will see the horn board was separate of the woofer board, and then they were stacked on top of each other to save some space and built into an enclosure which still ended up about 8"X 10"X 6" and next to some pretty large TUbe amps sitting in one pic with them hooked up you can see the comparison, they get rather large.... Good luck, and those caps and inductors are the sizes you are using, same physical sizes...
