Interesting idea. On the other hand on the latest SSD with hardware encryption the raw disk speed under Linux can be over 5 GB/s so on my laptop with 64 GB of RAM the full restoration from disk takes like 45 seconds. With LUKS it is like 2 times slower. Which is not a problem at all. So I do not see much value in memory encryption in suspend.
