Magnat Monitor 802 Improvements?

Hello,

I've been reading posts here for a while now, and now thought to register and ask a few questions.

I have 6 Magnat Monitor 802s in my home cinema and I like them quite well.
They are all driven by Behringer A500s, which I want to modify too.
The thing is I am not quite pleased with the heights.
My dad has two Quadral Signum Towers in his livingroom and the heights just sound
so much better.

Anyone has any suggestions on changing the tweaters on a budget?
Or maybe modifieng the crossovers?

Looking forward to your suggestions.
