I thought this same thing earlier. Lets say I had two VK-500's and was bi-amping the Vistas. I think the panels would sound just as good as my Vantages do now. They are the same panels. I am not hearing a better panel in the Vantage, just a better controlled one due only (in my opinion) to the bi-amping. They do have different woofers and enclosures so the Vantage would probably sound better, even with a stronger amp on the Vistas woofer. There is also a slightly different x-over but nothing that would change the panel that much. With the Vantage the x-over point is 400 vs. 450 in the Vista (I think thats how it went).
But the money is better spent with the Vantage vs. bi-amped Vistas, Vantages cost around $1300 more and you have the bass adjustment. Another VK-500 would be around $2200-$2500 (used agon) and you still wouldnt have the high-excursion woofers. Now you could get a cheaper amp, say for me a VK-200 for around $1000 but I still think it wouldnt sound as good as the Vantage (due to the woofer and enclosure) and wouldnt be as flexible. And those amp prices are used, if new double the cost of bi-amping. As we all know the Martin Logan does not buy used amps to power their Vantages so apples to apples is new vs. new.
You could get a pro-amp ($300-400), which is much less expensive, and plenty capable of high-end quality on the bass. Then you still have money to put towards a sub (used descent, $1500). Once you cross over at 80Hz, you likely wouldn't be able to tell the difference between the two. However, that is speculation, as I've never been able to do that test!
You're right too, though, that the woofers are different, and could perform differently above 80Hz, so it's hard to know. Also, I think the crossover point on the two speakers is different, which could favor either one, depending on preference.
I think they did a good job with price positioning to make both models attractive to people....and allowing Vista people to do a pseudo-upgrade to vantages for the cost of an amp.
For an apples to apples comparison, you'd need to get an unchassied bass amp of some variety, which can be gotten very cheaply.

per channel. Comes out to $300 or so. But that wouldn't mount so well on your Vista
Another alternative is the Crown XLS 402, which costs $400 but has a $120 rebate right now, bringing it to $280. Then you have money for some descent love!!! http://www.sweetwater.com/store/detail/XLS402/
