Swamp coolers require low dew points. They aren't that great. New heatpumps from American Standard, for example, can be 16 Seer, and actually higher SEER than that since they are 2-stage. You can also look at ground-water based systems.
Putting the duct work in conditioned space is a good idea. Insulating the duct work is also a good idea. Very important to get the right size unit too.
If the house is very "tight" you'll need an air exchanger.

Subject: [GBlist] Healthy Ducting
I am working on a new house in northern California. The summers are hot
and the owner is insisting on air conditioning. I had originally
planned on passive cooling, radiant floor heating in the slab. I also
wanted to use instant hot water in the master bathroom for shower and
tub needs.
They would like to have a ducted system which provides heating and
cooling.
I am concerned about air quality and energy conservation.
The house is large much to my dismay, so it probably needs multiple a/c
units if we
went the standard a/c.
Anyone had luck with swamp cooling in Northern Cal?
Suggestions are welcome!!
Barbara
