How about AAAs? If the battery box with the new train sets were a 6-AAA box instead of the rechargeable one?
6 AAA batteries have the same voltage but less capacity... you could take one of those square 9V batteries and potentially run your train, but only for a few minutes!
So I think that could work, the trains just wouldn't run as long. Some sort of adapter would be great, so that you can come up with your own solution to supplying 9V and then have it work with PF.
This is actually already possible, but requires modification to a PF cable - it's something we've discussed here, using the electrified rail with a dead 9V motor as a pick up and converting it to PF so that you could have the best of both worlds... an "infinitely" running train that can be controlled by remote and without the need to build a big, bulky battery box into your train. It's also possible to take an "old" LEGO battery box and use this conversion cable to operate PF (when I say that, really, we're specifically talking about the IR receiver, as simply connecting an old battery box with a PF motor was possible, using the conversion cable sold by TLG, just that "function" like IR wouldn't work).
But... going back to the OP, he asks for a simple solution... TLG actively took away the simplest solution and made it a lot more expensive and complicated.
I would argue the new system has several advantages... but simple is not one of them.
