If i where to run a 32bit OS on a 64bit kernel would there be any problems
with that? I'm not trying to convert the OS to 64bit, just would rather not
have to build multiple kernels if i dont have too. I'm talking x86_32 and
x86_64 btw too.

I guess you mean 32bit userspace with a 64bit kernel.
And that's no problem as long as "CONFIG_IA32_EMULATION" is set
The option is in the menu: Executable file formats / Emulations
and is called: IA32 Emulation

Just my $.02. I do this configuration for years on some machines.
The only problem I've ever met is that some drivers are broken to support this
configuration, some ioctls or mmap structures simply binary differs on 32 and
64-bit (due to different alignment and members size) and the driver can't cope
with that -- doesn't define ioctls independently on arch or let the structures
unaligned.
So make sure you won't use any proprietary blob which can't handle this (e.g.
nvidia is OK).
