We've got no hard information either way, but while Thranduil may dislike and mildly distrust dwarves, I don't think see where he has any reason to think they're allied with Sauron. No dwarves have fought on Morgoth or Sauron's side that we know of, and even they knew when to leave the dwarves alone. (Recall the dwarves in the Nirnaeth were so righteously angered by their king's death that they stopped mid-battle, marched off the field with his body in solemn procession, and none dared fuck with them, not even the balrogs.) So yeah, I think Thranduil's probably ok leaving dwarves to hold the Mountain provided they're a stabilizing influence in the region, not a destabilizing one.
I suspect bringing people from the Blue Mountains was doable - it's said earlier there's nothing a dwarf will stop at to regain his own, so I can't see 'needing to secure a few passes over the Misty Mountains or take the long way around through the Gap of Rohan' stopping them once they know the Kingdom under the Mountain is back in business.
