Is there explicit confirmation from CryptoBridge that they support a NXT base coin?
The concern is indirectly this quote:
NOTE: We do not currently support, ETH based chains (or tokens), NEO (or tokens), GAS or Cryptonight coins. These are all in development and will be announced when available.
I would not interpret that quote as guaranteeing they support all possible coin types other than the exceptions listed. They aren't lawyers. The general, informal impression given is that they do not necessarily support any coin type other than the likes of those already on their exchange.
Since they have listed many more minor coins than NXT, the absence of NXT is notable. Of course, they plan to list more types eventually, but it might take a lot more than 1 BTC and 2 weeks.
If not for that concern, listing on CryptoBridge would be great.
