How about diopters?
While diopters can be effective, they add a lot of flair unless you purchase the most expensive ones. In this case, you're really better off in using extension tubes since they don't add as much magnification to a macro lens as you'd hope. But for point & shoot cameras, they're a great addition.

One of the other options you can use is to get a "reversing ring" which will allow you to attach another lens to the front of your macro lens.
Actually, I believe what you're thinking about is a "Reverse Coupler". A "Reversing Ring" uses only one lens in reverse. And if you want to maintain auto functions, an automatic reverse ring is expensive. And since currently, theres not one made for manual use it's not a good alternative.
A "Reverse Coupler" is equally as useful on Point & Shoot cameras as it is on SLR's or DSLR's. And as you say, simple attaches the lenses by the filter threads to each other. But don't forget, you end up with a circular image, which needs to be cropped. This cuts down your file size, and reduces the size of prints you can make:

But here again, we're talking something which is about as expensive (or more expensive, depending on which model you get) than the Canon Mp-E 65mm. You can use a manual set with it, but I can assure you it's difficult to get the best results shooting live insects. So the 65mm is the best alternative for "ease of use" while maintaining the highest quality photos with maximum magnification. There's really not anything else that does the job as well.
For example shots, descriptions and more detailed information on various techniques, I invite you to look through my galleries here:
