It sounds like you want everything to just continue running. I don't see how that can be done. All of those in-kernel tables and structures would need to be migrated, and it follows, because there was a crash, that any of them might have been corrupted. Worse, you want this to save you when you try running a new kernel which crashes, and being a new kernel, it follows that any of those structures could be different; it might not be possible to create equivalent structures for different kernel versions.
If you're at all concerned at keeping the computer running, and I think that's your goal, then I think the best you can do is reset the hardware, boot an alternate kernel and restart applications as appropriate.
