📝 Original message:Yes, you can activate softforks at a given height.
I don't see any reason why you couldn't rebase to 0.16 directly.
The block version bumping was a mistake in bip34, you don't really
need to bump the version number. In any case, I would recommend
reading bip34 and what it activates in the code. IIRC the last thing
was bip65.
