Some general advice on a second tank

Hi everyone, it time for me to upgrade to my second tank and I've had such a great experience with IM all in one systems that I was thinking about purchasing another one. I currently have the nuvo 8 with an ai nano light an IM protein skimmer and recently purchased vortech mp10w. I have shopped around a bit and was looking into putting together a 57 deep blue but I quickly got way out of budget after wanting to add two ai hydra 52 lights. I have a budget of around 1500-2000 and I would like to stay on the lesser end of that. I'm looking at keep acropora and already have a lot of experience doing so just not in my own personal tank (I've taken care of friends tanks and set them up etc...) but without going on too much longer here is a list of equipment I was thinking about to start myself off with. Let me know if I'm going wrong with anything here as most of the stuff is new and I haven't heard anything good or bad. Also, I'm horrible when it comes to judging lights and the strength of them so I have no idea if a single ai hydra 26 will be strong enough or if I should get a hydra 52. I only want to run one light btw.
