Keep the Miyata as is and get a track bike.
the 912 was not TOL is was second or third rung. Shinamo 600 while nice was also not TOL. It was meant as a general purpose road bike that could be used either for light touring with an occaisional race. This type of bike is IMO the perfect canidate for conversion. Responsive enough to be fun to ride yet stable enough to not be exhausting, light enough to carry yet strong enough to lock up and give light abuse. Fender eyelets too. As and added bonus aero shifters make dealing with (NOT REMOVING) the braze on a snap.
I say convert it. It's a nice bike and it will be nice fixed. If you don't like it it can be nice geared again. Whatever you do don't listen to the hipsters and "get a track bike" when a conversion will suit you better. Unless you want a bike to ride a mile or two to a bar and then look good locked up outside or you plan on racing on a track a track bike is not going to be the right choice.
