I like:

Declan and Cooper but DP wont agree. Hudson is another favourite of mine that Dp wont agree on.. I got that name from someone on here. She started a thread on how to spell it.... Anyway,

The names we did agree on were:
Taite and Seth obviously and this little one will be Jett at this stage if it's a boy. I like Chase too but can't imagine looking at a bub named Chase, so it will probably be a middle name.
