You can still grow/shrink/grow and write the same value at a different time. I'd assume you need the tag at every element, every time. And I'd increase it, rather than try to keep the same. It's simpler, the effect is the same and the number of counters is far bigger than it'll ever be used.

And 64KB is more than enough RAM for everyone.
