Hello, I'm pretty certain that switching to the hardened profile won't cause any slot conflicts, it pretty much just enables some compiler flags ( PIE ( it's enabled in not-hardened profiles since 6.3.0 too iirc ) , stack hardening, fortify source, RELRO ) and hardening flags on a few packages ( e.g. glibc ). Please try it again, maybe the output of emerge --info and the output of your world emerge ( or just the error message , both as pastebin or something ).
I'm not quite sure if I understand the second part correctly, but I guess you want to compile packages on your workstation for that smaller box? In that case it doesn't matter which kernel your host uses, just make sure to choose the correct -march value. You don't have to run the hardened kernel for the hardened profile to work ( although it greatly enhances it - but maybe not for long since GRSEC stopped publishing their patches ).
