Talk me out of it: MTM using two Xt Mini Centre channels

So I've been toying with the idea of trying another coaxial driver when I heard (somewhere on this forum)
about the Tannoy XT Mini, which is a 4" Dual Concentric driver with a 0.75" tweeter that can reach upto
50ish KHZ! Apparently that driver has amazing imaging capabilities probably do to the smaller mid being
able to go higher and my guess is using a shallower slope.



Using my DEQX, I've been playing around with different drivers up top and really liked the TB 0.5" Silk tweeter. There's just something very nice to my ears about having that effortless top octave without the

beaminess of the larger tweeters. Even my KEF LS50's as much as I love them could have a little more air

in the top end.





And then I saw these on the TANNOY site:

Now I've been reading about some of the drawbacks on MTM's, but I've read that alot of

that can be ameliorated using a coaxial in the center because of the lower crossover.



The XT mini centre comes off the plinth and I'll bet I could turn it sideways and use it like an MTM

configuration. Are there any drawbacks to this? I cant see why this speaker would perform much different than a left or right main. Here's the specs:
