I am curious if you thermally destroyed them or mechanically. Thermally is compensation for wind, mechanically crossover point/slope. My guess is thermal matching Jimi's but of course I can't be 100% sure. What would help this is if you could fit a larger tweeter. That Seas while fine as a neo just isn't stellar (but when you got them it isn't like there were other good choices unless you wanted to spend D2904 type dough). Of course that would take more space. What I don't know is how the Evil is on power handling. My guess is that it should be better than that Seas all the way around but if you rapidly destroyed those having some more headroom wouldn't be terrible.
I am not sure metal buys you anything. Sure some top end sparkle, but you are probably really striving to have more on the bottom than on the top. The top rarely causes either thermal or mechanical concerns...
