Is it possible to de-rate a pressurized aircraft?

Thanks for the update, Ed. Was curious about that.

It's not about breaking the bank, so much as justifying it. I'm only going to be flying about 72 hours or so, in other words 6 hours a month. So I'm trying to figure out if it's really worth carrying something like a pressurized model if they really are 2 times the cost of Maintenance compared to yours. For those hours it may not make sense to be spending 16 or 18 thousand in maintenance alone on a normal basis.
