It is not advisable to use ceramic capacitors in DC-DC switching circuits to replace electrolytics. Tantalum is ok.

Also, you dont hand-solder those capacitors down with a wand. 

You have to use solder-paste, and reflow new ones in place of the old ones. 
So Tantalums are OK? I'll keep that in mind.

I do use solder paste, so depending on the task and cap physical sizes, lets see how it goes. I'll try it out on a busted up Duo230 first.
