No.

The two are different things, although arguably there should be more 
integration.

The tunable mechanism exists to allow parameters to be set before the 
kernel starts.
Things that are set with tunables tend to be things that used to be 
statically compiled
into the kernel; they're not adjustable once the kernel's up and 
running.

It makes sense to export the values set by tunables into the sysctl 
MIB, but by their
very nature they're not suitable for conversion to sysctls.
