In a one gallon batch should get you around 14%+ ABV
A big beer is already going to have plenty of residual sugar, that much crystal would be cloying. I wouldn't go over 8oz, and preferably closer to 4-6oz, if any. Not sure on OP's efficiency so assuming around 75%, I'd opt for something closer to this
should put you around 1.126 for OG, I wouldn't go any higher than that if you want to be sure it'll finish. make sure to mash low and keep fermentation temps down (no higher than 68F internal temp).
