A Justified Conundrum

I am in the midst of a conundrum.  Justified is the second book in my three-part Magnified series.  It's paranormal fantasy with a fun twist and I am extremely excited for Magnified, book one, to come out.  I don't have a release date just yet, but I'm currently working on the second round of edits, which means a release date should be coming soon.  The problem is that I don't know what to do with Justified.  I really, really like the story and I've completed writing, editing, and formatting it.  Justified is one hundred percent ready to be submitted to Less Than Three Press.  Except, LT3 is already swamped with my submissions. 

At this moment I have two books in the midst of the editing process: Dragon Detective and Magnified.  I also have two books that have been accepted, but have not yet taken that first step towards publishing: The Case of the Wandering Wolves and Elemental Ride.  In addition to those four stories, I have also submitted five more stories: Ner Li, a short story for the Sharing the Season Call, Ge-Mi: Part One, a futuristic sci-fi story, and the next three stories in my Supernatural Consultant Series, Dragon Soldier, Dragon Adventure, and Dragon Home.  That is nine stories in total.  Oh, before I forget, Dragon Dilemma is in the pipeline too.  It's going to come out on June 1, 2016 and is currently somewhere in the copy editor's queue.  That is ten books total already on LT3's radar, which feels a little ridiculous.  If I do the math, that equals almost three years of future releases (if LT3 accepts them all).  

So now I'm looking at Justified and I don't know what to do.  I can't look for another publisher since Magnified is contracted with LT3 and splitting up a series like that would be beyond silly.  Yet, I also don't feel quite right adding an eleventh book to my list with LT3.  The obvious answer would be to wait on Justified until that large to-do list begins to get whittled down, but at the same time Justified is complete and letting it sit on my computer for a few extra months or even years might bog it down.  I'm also starting a new job in a week that will keep me much busier than I am now and I'm worried that submitting Justified will get forgotten amid all my new responsibilities. 

What do you think I should do?  Should I send it to LT3 anyway and hope they don't tell me to cool it for a while?  Should I wait to submit despite my fears of forgetting about it?  I really could use some advice.
