Since the maristar has generously sized reflectors (for a complete fixture) it's able to decently light your generously sized tower of rock. I don't think any canon styled LED pendant is going to be a fit over your tank due to your scaping (especially the center of the tank). 
 
Even tho I haven't seen the 350 in action yet it is worrisome to think about how much intensity is lost when trying to achieve a slightly blue overall colour temp. At the same time I feel my 150 could use just a tiny bit more blue but supplementing an array of 150s with some blue strips will likely produce colour banded shadows so it's lose/lose. Decisions decisions!
