Not quite - Your design does not allow otherwise.

You could redesign your code in such a way it doesn't have these
limitations/restriction attached, e.g. 
* by rewriting your code in inline-asm (There you can utilize sizeof())
or
* by using helper const variables being set up in C and refer to them in asm or
inline-asm
or
* by re-writing everything in C, such that only very few atomic ops (functions)
would have to be needed.

There probably are many more ways.
