I see a couple of options. 

1. Go for the gold.  Let's open it up and compete with the other coins that use this algorithm.  You seem to have heart and love the game so this could be an option especially if you have a bunch of us that will back the coin.

2. Implement a multi algo approach such as Digibyte. 

I know this stuff is hard to do.  In 2014-15 I started a coin that was a clone of Mintcoin called Cornerstonecoin.  The community can be harsh and I gave up.  However, what you have started could gain steam.  I also know you are doing this for the fun of it and your love of the concept.  If you really want it to succeed, it will.  Personally, I would go with something similar to option 1.  What have you got to lose at this point?
