Sansui SP-2500 - Keep Original, or Modify?

In-looking (locally) for a Heresy-sized, high efficiency floor speaker (little kids == no towers, stands), I've come-across a 99% mint condition pair of SP-2500s, and for a song. Admittedly I am not one to keep things 'original', if quality is being sacrificed. I was thinking of rebuilding the mid/high section with new mid drivers, and a ribbon tweeter (and removing the HF 'lens'). Some crossover work, as well, of course. 

Does anyone own SP-2500's, and have you modified them in a way that is to your liking? Or would a guy be better keeping these, as-is?

Thanks!

Unless you know a lot about crossover design, you shouldn’t be swapping drivers. I owned a pair of 2500’s for a couple of years for my garage, and I don’t think that they’re worth a lot of fuss.

Dude, if you are going to do that, you are only keeping the box. Um, sure, but do you know how to do speaker design? It's not just driver swapping.

If you really want to build a speaker I strongly suggest you build from a kit instead and leave these for some one who wants them as is.

I have a pair in my speaker collection! Mine are staying unmolested as examples of 70's Japanese "kabuki" sound! I say leave the drivers alone - just upgrade the crossovers with modern caps and inductors. Otherwise you will ruin the "flavor" by changing the drivers!

Buy something else, they were decent back in the day. Too many drivers over the same frequency range = unclear/fractured sound. If you want  3-way, go with 3 drivers.

Or at least buy the speaker cookbook first so you know what you are in for.
