Sorry I couldn't reply earlier..
As mentioned in the OP, can see whether making Home "resident" results in oom_adj status change:
Usually Home (eg: nova launcher) stays as a HIDDEN app, so easily killed when RAM goes down..
After making it "resident", it becomes a FOREGROUND app.
*If this is not happening, maybe something wrong with Xposed module setup. If it gets killed even as a FOREGROUND app, maybe the Minfrees are set too high for the FOREGROUND app shutdown (described in the OP). Also, try Greenify to hybernate unnecessary apps. Jar patching is a another option to make Home stay in RAM.
Frankly, now I'm on custom KK ROMs without using any of the tweaks mentioned in the OP and having very good multitasking and free RAM. Available for LBL too. May as well give 'em a try :P
