Okay, i've come up with two different configurations for the metal cone concept.
1: the way you guys say I should do it. It has the Mundorf hifiAMT®25CS2.1-R as tweeter, two Seas Excel W15CH001s for midrange and four Scan-Speak 22W/8857T00. The 22W is not the biggest model of the Revelator line but it is big enough and has a big enough Sd. In terms of speed in practice they will be equal because the bigger Sd of the 26Ws compensates for it's slightly slower response and vice versa. And you will say "BUT THE 26W IS MORE LINEAR", maybe, but they both have the same Xmax and wide suspension. And anyway, a woofer is designed as a whole, to work best the way it is, so the smaller 22W is of equal sound quality as the 26W just smaller. The resulting sound of a bigger woofer more depends on the application I think. I can already feel the death threads for saying this coming in.
And I came up with another one with smaller mid woofers, this one is gonna be very controversial.
Again, the Mundorf hifiAMT®25CS2.1-R as tweeter, two Eton 4-308s for midrange and six Eton 7-208s for mid bass. Why? Well, as I said before, I want top notch transient response from this system. And don't get me wrong, the Revelator woofers are blazingly fast, though, there's much faster, and I want that. The Seas Excel W22EX001 is slower than the Revelator and technically is just not as good entirely. The W18EX001 except for the Accuton driver is the quickest I know of, though it only goes to 90 Hz in a sealed box. So I looked at the Eton Arcosia 7-208. It's a smaller 7" but it's of top notch quality, it's right up at the level of Accuton though with magnesium cones, which is good. Six of them have a pretty decent Sd of 822 cm2 compared to the 880 cm2 of four 22Ws. With a sensitivity of 89 dB they are rather efficient, up there with Satori. They have extremely low distortion and overall their sound quality is the best on the market and, they go low enough in a sealed box and they are blazingly fast, even faster than Ellipticor and because of the combined Sd of 822 cm2 they don't have to move particularly much more than bigger 22Ws would so they really will be much faster in practice.
And yes you will start craving about them not have as wide of a suspension or as big of a Xmax as bigger woofers like the 22W but really, in simulation, at a level of 94 dB, which in a room is absolutely rocking, even at a small concert in a theatre hall, they are barely even moving. According to simulation only 0,4 mm at the lowest they will go, 80 Hz.
About the Eton midrange I'm not too sure. It's from absolute top-notch quality and will offer the best sound quality on the market from a magnesium cone, though, it's only a 4". I know 4" can sound good and the sound characteristic more has to do with integration, frequency response and dispersion but I wonder if they will have that nice chestyness and snap to them. Though, lower vocals go to under 100 Hz and actually lay within the 100~400 Hz for the biggest part, do you think the mid bass will mainly make up for that chestyness?
Really, both these configurations are absolutely top-notch as far as metal drivers of their size go. They are just different. The configuration with the 22Ws will have that weight and supposedly linearity (within the like 0,2 mm they will move on a regular basis) of bigger woofers to it that you seem to crave about so much. The configuration with the Eton drivers will just better offer that pin-point transient response and though it's size is something to work around, the midrange will probably offer slightly better transparency, clarity and detail just because of it's quality. The Seas Excel drivers already are top notch and Eton Arcosia and Seas Excel are quite similar, though Eton just slightly takes it up another notch.
Which one will be desirable neither you or I can decide. The only way to choose one of the two is by hearing them.

Before going with this project, you can try one synergy horn with 1"CD and 2 or 4 mids (Visaton FRS 8M is cheap and good), maybe you can borrow the CD so that you don't spend money.
Not expensive to try and maybe you will like it more than what you have now.
