When my dehumidifier died I happened to find out the county was having a trade in event for better economical versions. I no longer live in that house but I know I went through two dehumidifiers in our stone walled basement in the 20+ years we lived there. The second one was sold with the house. It sat on a stand I built for it that was about 24-28" tall and drained into large tub that was emptied by a sump pump into the clothes washer drain pipe. Perhaps the elevating idea has some merit. I also cleaned mine whenever the light went on. I think the second one was a Midea but dont hold me to it.
TL/DR
You might want to see if your environmental services in your area are having any turn in options. Elevating is looks like a good thing to do. Midea has good reviews.
