VAC bans are specific to the game you got them on afaik, while it will be shown on you profile they should not block you from connecting to servers in a different game from where you got one. So by all means it should be possible to play on your old account.
I was slightly off, but the point still stands. It should still work given csgo is not on the same list as tf2 so uhh...
If you ARE that dead set on moving them over, it should be as simple as getting both accounts on a server and trading your hub items over 1 at a time (unless you have any custom titles that are not tradeable of course).
