From what I understand, early imaging machines were pretty crummy. New ones are supposed to be better and I badly want one. But they are expensive.
There are a number of different options for soft molds for BTEs and RICs. No soft ITEs. You can put a rubbery soft coat onto an ITE, but it’s thin and is more for feedback than for comfort. I’m not sure a soft mold would overcome your ear swelling issue, though, if it swells so much that you can’t get whatever you use regularly into the ear. The soft molds are giving, but not spongy, and can often be MORE difficult to get into the ear because of increased friction. You’d almost need a morning mold and an evening mold.
